NUMBER 2
Use distribution property to simplify the expression, (-8) should be distributed to 10x and (-3)
-8(10x - 3)
= (-8 × 10x) - ((-8) × 3)

Then multiply the distributed numbers
= (-8 × 10x) - ((-8) × 3)
= -80x - (-24)
= -80x + 24
The answer is option b

NUMBER 3
Use distribution property to separate 4 from 16x - 16, divide 16x-16 by 4 to separate it
16x - 16
= (4 × 4x) - (4 × 4)

Then exclude 4 we want to separate
= (4 × 4x) - (4 × 4)
= 4(4x - 4)
The answer is option c

NUMBER 4
32 and 56 has 8 as the greatest common factor. We should exclude 8 from -32m + 56p
-32m + 56p
= (8 × -4m) + (8 × 7p)
= 8(-4m + 7p)

Now exclude -1 from inside parenthesis
= 8(-4m + 7p)
= 8(-1 × 4m) + (-1) × (-7p)
= -8(4m - 7p)
The answer is option c

My mom is mom like a 55

The answer should be 5.
