Answer:
Step-by-step explanation:
(-5)^2 - (-5^2)
25 - (-25)= 25 + 25 = 50
26 and 32. The product (multiplied together) is 832.
4
Plug in each given value into the expression to see if it is true.
Set given: {2 , 3 , 4}
Equation given: x + 2 = 6
First, plug in 2 for x. When x = 2:
x + 2 = 6
(2) + 2 = 6
4 ≠ 6.
Next, plug in 3 for x. When x = 3:
(3) + 2 =6
5 ≠ 6.
Finally, plug in 4 for x. When x = 4:
(4) + 2 = 6
6 = 6 (True).
In the given set, only 4 complete the equation.

3(-3 + 5x) -1 (4 - 4x)
Simplify each term by first using the distributive property with each set of parenthesis:
3*-3 + 3*5x - 1*4 -1* -4x
Now do the multiplications:
-9 + 15x -4 + 4x
Combine like terms
15x +4x - 9 -4
19x - 13
