Jennifer wrote the expression: (2x3 + 3x2 + 2x – 4) – (x3 – 2x2 – x – 1). What is the simplified form of this expression?
Answers
2x³+3x²+2x-4-(x³-2x²-x-1). Using the distributive property, we get
2x³+3x²+2x-4-x³+2x²+x+1
Adding and subtracting like terms (e.g. x³+3x³=4x³), we get

The undefined terms line and plane are needed to precisely define which mathematical term?
line segment
perpendicular lines
parallel lines
ray
Answers
The correct answer is:
parallel lines
Explanation:
Parallel lines are two lines in a plane that never intersect. This means the definition uses the undefined terms "line" and "plane."
The undefined terms line and plane are needed to precisely define which mathematical term will be parallel lines so option (C) will be correct.
What are a line and plane?A line section that can connect two places is referred to as a segment.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
A plane is a surface that is straight in nature a plane has a certain area but in most cases.
We know that parallel line are those lines which not intersect and lies on a plane.
Hence there are two things that are needed first is a line and the second is a plane the plane should be single for both lines not different.

You miss 3 out of 10 questions on a science quiz and 4 out of 15 questions on a math quiz. Which quiz has a higher percent of correct anwsers.
I did 3/10 so 0.3 and 4/15 which is 0.266... so would it be the science quiz???
Please explain
Answers
Since 3/10 and 4/15 is the amount you missed you have to subtract that by 1.
1 - 0.3 = 0.70
1 - 0.26 = 0.74
So, you scored higher on the math quiz.

I suck a writing proofs in geometry.... please someone explain it to me, i cant seem to reconize what's going on. I need major help in properties of congruent proofs.
Answers
In earlier mathematics courses, you have learned concepts like the commutative or associative properties. These concepts help you solve many types of mathematics problems. There are a few properties relating to congruence that will help you solve geometry problems as well. These are especially useful in two-column proofs, which you will learn later in this lesson!
The Reflexive Property of Congruence
The reflexive property of congruence states that any shape is congruent to itself. This may seem obvious, but in a geometric proof, you need to identify every possibility to help you solve a problem. If two triangles share a line segment, you can prove congruence by the reflexive property.

Four friends purchase 18.4 pounds of peaches. The peaches cost $1.75 per pound. The friends share the cost of the peaches equally. How do I do this!!!!?????????
Answers
Answer:
Cost per friend = 8.05 $
Step-by-step explanation:
Four friends purchase 18.4 pounds of peaches.
The peaches cost $1.75 per pound.
Total cost of peach = Total pounds x Cost of peach per pound
Total cost of peach = 18.4 x 1.75 = 32.2 $
Number of friends dividing the cost equally = 4
[tex]\texttt{Cost per friend = }\frac{\texttt{Total cost of peach}}{\texttt{Number of friends dividing the cost equally}}\\\\\texttt{Cost per friend = }\frac{32.2}{4}=8.05\$[/tex]
Cost per friend = 8.05 $

What is another way to write the expression r⋅(18−3) ?
(r⋅18)−(r⋅3)
r⋅18−3
(r⋅18)⋅3
(r⋅18)−3
Answers
The other way to write the expression r⋅(18−3) will be (r⋅18)−(r⋅3). Option A is correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that the expression is, r⋅(18−3)
We have to expand the expression in order to write the expression in the other way,
The expanding form can be used to indicate the value of each digit in a number in arithmetic. Numbers that are expressed as the sum of each digit multiplied by its place value are known as expanded numbers.
There are the different identity used in the expanded form as,Use the following identity as
a(b-c) = ab-ac
=r⋅(18−3)
=(r⋅18)−(r⋅3)
Thus, the other way to write the expression r⋅(18−3) will be (r⋅18)−(r⋅3). Option A is correct.
