Answer:
A. 2(16+12)
Step-by-step explanation:
1. 2x16=32
2. 2x12=24
3. 32+24=56
A. 2(16 + 12)
If we look at choice A, it says 2 times 16 + 12.
When we solve this, 2 × 16 = 32 + 2 × 12 = 24, we get 32 + 24 because we used the distributed property on answer A.
Answer:1 1/8
c - 13 = - 2
grouping of like terms
c = -2 + 13
c = 11
-185
To complete the square, we need to have the equation set up like this:
x^2 +4x =9
To do that, we'd need to move the 4x to the left side producing
4x + x^2 = 9
And that can be rewritten as
So the term that needs to be moved is -4x
