Answer: 8x + 20y
Step-by-step explanation:
Since there is no answer after =, I'll assume you have to give your own.
![4(2x+5y)=?](https://tex.z-dn.net/?f=4%282x%2B5y%29%3D%3F)
![(4*2x)+(4*5y)=?\\8x+20y](https://tex.z-dn.net/?f=%284%2A2x%29%2B%284%2A5y%29%3D%3F%5C%5C8x%2B20y)
Answer:
3
Step-by-step explanation:
This can be represented by the expression 4d.
Distribute -5.5(2-6x) first
-5.5 x 2 = -11 & -5.5 x -6x =33x
=> 33x - 11
33x - 11 -2.5x
subtract common like terms
33x - 2.5x = 30.5x
Answer: 30.5x -11

Answer:
f(x)·g(x) = x³ +x² -2x -2
Step-by-step explanation:
Substitute the function definitions and simplify.
f(x)·g(x)
= (x +1)(x² -2)
= x(x² -2) +1(x² -2)
= x³ -2x +x² -2
f(x)·g(x) = x³ +x² -2x -2
