Check all that apply. Distribute 9, by multiplication, to the variable, a, and to the constant, 8. Write the two multiplications, 9(a) + 9(8) The expression 9(a) is written as 9a. The expression 9(8) equals 72. The equivalent expression is 9a + 8. The equivalent expression is 9a + 72.

the answer for this question is 38

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
