The correct matches are shown in the picture after simplification of every expression.

<h3>What is an expression?</h3>

It is defined as the combination of constants and variables with mathematical operators.

We have expressions shown in the picture:

First expression:

= 12x + 8 - 7x - 10

= 5x -2

Second expression:

= 17x/3 + 17 - 2x/3 - 15

= 5x + 2

Third expression:

= 8 - 12x - 10 + 7x

= - 5x - 2

Fourth expression:

= 9 - 9x/2 -x/2 - 7

= -5x + 2

Thus, the correct matches are shown in the picture after simplification of every expression.

What are the solution(s) of –x2 + 2x + 3 = x2 – 2x + 3?
Leviafan [203]
-x^2+2x+3=x^2-2x+3  add x^2 to both sides

2x+3=2x^2-2x+3  subtract 2x from both sides

3=2x^2-4x+3  subtract 3 from both sides

2x^2-4x=0  factor

2x(x-2)=0

So x=0 and 2

Erin’s car uses 6 gallons of gas for every 138 miles she drives.which equation could be used to find how many gallons,g, Erin ne
gladu [14]

The equation that could be used to find how many gallons Erin would need to drive 92 miles is 92 = 23g (option c)

<h3>How many gallons is needed to drive 92 miles?</h3>

The first step is to determine the gallons needed to drive 1 mile. To do this, divide the  6 gallons by 138 miles. Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷.

Gallons needed for 1 mile = 6/138

In order to determine the gallons needed for 92 miles, multiply the ratio gotten in the previous step by 92

(6/138) x 92 = 4 gallons

The option that gives 4 gallons is : 92 = 23g

g = 92 / 32 = 4

Always ? Sometimes? Never <br> Explain
Stels [109]

Answer:

Sometimes

Step-by-step explanation:

Quadrilaterals are shapes with four sides.

This means some quadrilaterals will have 4 equal sides, others will have <em>no </em>equal sides!

There is no rule determining side length equivalence in quadrilaterals. But those may be sub-classified as other shapes.
