Answer:
B
Step-by-step explanation:
The associative property states that we can add numbers in any way we want to still get the same sum, so the parenthesis here can essentially be tossed out to get 3x+2-5=3x-3. However, make sure, for example, that you don't add x and 1 together in 3(x)+1 as you still have to multiply the x with 3 before adding the 1 according to PEMDAS

Answer:
Answer: Sample Response: The height of the triangle will be twice the height of the rectangle. The area of a triangle is ½ bh and the area of a rectangle is bh. If the bases are the same, then the height of the triangle has to be double that of the rectangle in order to get the same area.
Step-by-step explanation:

9e + -7 = 7e + -11
Reorder the terms:
-7 + 9e = 7e + -11
Reorder the terms:
-7 + 9e = -11 + 7e
Solving
-7 + 9e = -11 + 7e
Solving for variable 'e'.
Move all terms containing e to the left, all other terms to the right.
Add '-7e' to each side of the equation.
-7 + 9e + -7e = -11 + 7e + -7e
Combine like terms: 9e + -7e = 2e
-7 + 2e = -11 + 7e + -7e
Combine like terms: 7e + -7e = 0
-7 + 2e = -11 + 0
-7 + 2e = -11
Add '7' to each side of the equation.
</span><span>Combine like terms: -7 + 7 = 0
0 + 2e = -11 + 7
2e = -11 + 7
</span><span>Combine like terms: -11 + 7 = -4
2e = -4
Divide each side by '2'.
e = -2
Simplifying
e = -2</span>
