A. 4y(2y + 5) = 4y(2y) + 4y(5) = 8y² + 20y

B. 7a(3a + 8b) = 7a(3a) + 7a(8b) = 21a² + 56ab

C. 13x³(3y + 2x²) = 13x³(3y) + 13x²(2x²) = 39x³y + 26x⁴ units²

D. 7m²(3m - 5) = 7m²(3m) - 7m²(5) = 21m³ - 35m² units²

Ok done. Thank to me :>

When you subtract 22 from a number and the result is doubled, the answer is 6 more than the original number. What is the number?

Karolina [17]

You have to write two equation:
'substract 22 from a number'
$X-22=Y$
and:
'the result is doubled, the answer is 6 more than the original number'
$2*Y=X+6$

then you change 'Y' in 2nd equation for left side of 1st equation:
$2*(X-22)=X+6$
count it and you get:
$2X-44=X+6$
This means that X=50
The original number is 50.
