Step-by-step explanation:
p² + q² + 5(p² + q²)
= 1(p² + q²) + 5(p² + q²)
= (1 + 5)(p² + q²)
= 6(p² + q²).
One can solve this by first using order of operations, and then combining like terms.
First is parenthesis
9x + 2x(9) - 2(9x)
Now we do the multiplication
9x + 18x - 18x
Now we combine like terms
9x

Answer:
D = 4.2
Step-by-step explanation:
-5.5 ( d - 2 ) = - 12.1
-5.5d + 11 = - 12.1
11 + 12.1 = 5.5d
23.1 = 5.5d
d = 23.1 ÷ 5.5
d = 4.2
