Answer:
a=11
Step-by-step explanation:
8(3a + 7) = 8+3(6a - 6)
24a+56=8+18a-18
24a-18a+56=8+18a-18a-18
6a+56=8-18
6a+56=-10
6a+56-56=-10-56
6a=-66
6a/6=-66/6
a=-11

Product of the numbers is 15
<u>Step-by-step explanation:</u>
Step 1:
Let the numbers be a and b. Given that, the sum of the cubes of the 2 numbers is 152 and the sum of the 2 numbers is 8. Form equations out of the given data.
⇒ a³ + b³ = 152 and a + b = 8
Step 2:
Use identity a³ + b³ = (a + b)³ - 3ab(a + b). Substitute the values in this identity.
⇒ 152 = 8³ - 3ab(8) = 512 - 24ab
⇒ 24ab = 360
⇒ ab = 360/24 = 15
