Show and explain your steps. PLEASE!!!
Answer:
[tex]3x^4-7x^3+x^2+2x+11[/tex]
Step-by-step explanation:
[tex]3x^2(x^2 - 4x - 2) + (5x^3 + 7x^2 + 2x + 11)[/tex]
First, I will expand the expression [tex]3x^2(x^2 - 4x - 2)[/tex]
[tex]3x^2(x^2 - 4x - 2) \\3x^4-12x^3-6x^2[/tex]
So, we got
[tex]3x^4-12x^3-6x^2+ 5x^3 + 7x^2 + 2x + 11[/tex]
Adding similar elements, we get:

Twenty eight slips of paper are numbered 1 through 28 and are distributed among a group of people. A random number generator is used to select a single number between 1 and 28, inclusively
A fair decision is made using this process
How many people could be in this group?
A. 3
B. 6
C. 7
D. 12
Answer:
Option D, 7, is the right answer.
Step-by-step explanation:
It is given that 28 slips of papers are numbered through 1 to 28.
Accordingly, there are 28 numbers.
For a fair decision, the number of slips with each one must be the same.
Therefore, the decision will only be fair if the number of people in the group is a factor of 28.
The factors of 28 are - 1, 2, 4, 7, 14 and 28.
In this way, 7 is the only factor of 28 among the given options.
Hence, the answer will be 7.

In a rectangle ABCD the diagonals intersect each other at point O, E is a midpoint of the side AB , and m∠BAC = 50°. Find the measure of angle EOD.
Answer:
130°
Step-by-step explanation:
In the picture attached, the rectangle can be seen.
We know that m∠BAC = 50°, then m∠ADB is also 50°. m∠AOE must be 180° - 90° - 50° = 40°, and m∠OAD = 90° - 50° = 40°, then m∠DOA = 180° - 40° - 50° = 90°. Finally m∠EOD = m∠DOA + m∠AOE = 90° + 40° = 130°

solve the following system x=3 y=3x-1
Answer:
x = 3
y = 8
Step-by-step explanation:
Since it gives you x, you need to plug in the number given for it into the equation:
y = 3x - 1
y = 3(3) - 1
y = 9 - 1
y = 8
So now you have, x = 3 and y = 8
Which of the following is(are) the solution(s) to 4 |x+3|>8

4/4 |x+3|>8/4
|x+3|>2
Absolute value inequalities have 2 solutions, one positive and one negative
Remember to flip the inequality when finding the negative solution

The statements that are true about the considered figure (given below) are given by: Option C: It is a triangular prism, Option F: It has 5 faces
What is a triangular pyramid?Take a traingle. This is a base. Now take 3 triangles such that each of them are connected to one-one side of the first traingle and when they're taken together, they form a closed object, called as a triangular pyramid
What is a rectangular pyramid?Take a rectangle. This is the base. Now take 4 triangles such that each of them are connected to one-one side of the base rectangle and when they're taken together, they form a closed object. That shape is called rectangular pyramid.
What is a triangular prism?Connect three rectangles edge to edge. Now close their triangular mouths from both ends. That shape is called a triangular prism.
What are vertices, faces and edges?Faces are planar mathematical objects. Like a triangle, a rectangle etc. Edges are those line segments, which are on the edge of the faces (of some object considered).
Vertices are points of intersections of different edges.
The missing figure is attached below.
It consists of 3 rectangles joined edge to edge, and have two triangular ends in the shape they form, thus, making a triangular prism.
There are 6 vertices of a triangular prism, here for this figure, they're named as A,B,C,D,E,FThere are 9 edges of that object AB, AC, AE, BF, BC, CD, ED, FD, EFThere are 5 faces (2 triangles and 3 rectangles).

Answer:
39 ft²
Step-by-step explanation:
Area of a triangle = 1/2bh
Let:
base = b = 4 ft
height = h = 3 ft
Solve for the area of the triangle:
A = 1/2(4)(3)
A = 2 * 3
A = 6 ft²
Area of a rectangle = bh
Let:
base = b = 9 ft
height = h = 5 ft
Solve for the area of the rectangle:
A = (9)(5)
A = 9 * 5
A = 45 ft²
Subtract the area of the triangle from the area of the rectangle:
45 - 6 = 39 ft²
39 ft² is your answer.

Write the first six terms of the sequence.
ao = -5, An = 3an-1 + 12
Answer:
The first six terms of the sequence are -3, 3, 21, 74, 234 and 714
Step-by-step explanation:
Given the initial value a0 = -5 and the general form of the sequence given as An = 3an-1 + 12
To get the first six terms of the sequence, we will substitute for n=1 up to n= 6 in the general equation.
when n=1
A1 = 3a(1-1)+12
A1 = 3a0+12
A1 = 3(-5)+12
A1 = -15+12
A1 = -3
when n=2;
[tex]A2 = 3a(2-1)+12\\A2 = 3a1+12\\A2 = 3(-3)+12\\A2= -9+12\\A2= 3\\\\A3= 3a(3-1)+12\\A3= 3a2+12\\A3 = 3(3)+12\\A3= 9+12\\A3= 21\\\\A4= 3a(4-1)+12\\A4 = 3a3+12\\A4= 3(21)+12\\A4= 63+12\\A4 = 74\\\\A5= 3a(5-1)+12\\A5 = 3a4+12\\A5= 3(74)+12\\A5= 222+12\\A5 = 234\\\\\\A6= 3a(6-1)+12\\A6 = 3a5+12\\A6= 3(234)+12\\A6= 702+12\\A6 = 714\\[/tex]

An investing group has $50,000 to invest. They put the money in an account that has an annual interest rate of 6%, compounded monthly. How much money will the group have at the end of 10 years?
The investing group will have $90970 at the end of 10 years.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
We can use the formula for compound interest to solve this problem:
[tex]A = P(1 + r/n)^(^n^t^)[/tex]
where A is the total amount,
P is the principal
r is the annual interest rate,
n is the number of times the interest is compounded per year, and
t is the number of years.
P = $50,000, r = 0.06, n = 12 and t = 10.
Substituting these values into the formula, we get:
A = 50000(1 + 0.06/12)¹²⁰
A = 50000(1.005)¹²⁰
A=$90970
Therefore, the investing group will have $90970 at the end of 10 years.

Choose 1 answer:
A. 2x(3x + 5)
B. (2x)(3x)(5)
C. 6x^2+ 10x
Answer: a
Step-by-step explanation:
The expression 2x(3x) + 2x(5) is factored into 2x(3x + 5). Hence, the correct option is A.
The expression 2x(3x) + 2x(5) can be written in factored form by taking out the common factor, which is 2x. The factored form is 2x multiplied by the sum of 3x and 5, which is represented as 2x(3x + 5). This matches with option A of the choices provided.
