Answer:
14, 7, 28
Step-by-step explanation:
Answer:
-9
Step-by-step explanation:
y = 8
x = -3
- 2(2-y)-x = ⇒ replace x and y with their values
- 2(2 - 8) - (-3) = ⇒ solve parenthesis
- 2(-6) + 3 = ⇒ multiply
- -12 + 3= ⇒ add
- - 9 ⇒ answer
Yellow is the correct answer, I think.
Answer:
7, 13 3,7 17,3 13,2
Step-by-step explanation:
Answer:
No.
It's x^4 - 4x^3 + 7x^2 - 28x.
Step-by-step explanation:
(x - √7 i)(x +√7i)
= x^2 + √7x i - √7x i - 7 i^2
= x^2 - 7 * -1
= x^2 + 7
g(x) = x(x - 4)(x^2 + 7)
= x(x^3 + 7x - 4x^2 - 28)
= x^4 - 4x^3 + 7x^2 - 28x.
