Step-by-step explanation:
by complete angle
x+38+52+220=360
x+310=360
x=360-310
x=50
Answer: The answer is 1,037. You did good with the first three steps but you need to do the same for the last step, because you have 21 you have to find how many times 3 goes into it, which would be 7, and that gives you your full answer of 1,037.
Answer:
4 - 4x³ + 20x² - 20x
Step-by-step explanation:
(g × f)(x) = g(x) × f(x) = (x³ + 5x)(4x - 4)
Each term in the second factor is multiplied by each term in the first factor, that is
x³(4x - 4) + 5x(4x - 4) ← distribute both parenthesis
= 4 - 4x³ + 20x² - 20x
This can also be done using FOIL, that is
(x³ + 5x)(4x - 4)
= 4 - 4x³ + 20x² - 20x
