Answer:
5x³ + 5x² - 55x - 15
Step-by-step explanation:
simplify the expression:
5(x − 3)(x² + 4x + 1)
use the distributive property to multiply 5 by x-3
(5x - 15) (x² + 4x + 1)
Use the distributive property to multiply 5x−15 by x²
+4x+1 and combine like terms
5x³ + 5x² - 55x - 15
================
For number 1. Is 21 = 21
Number 2. 12/25
Number 3. 9
Number 4. 64 =64
Number 5. 15 = 5
Number 6. 4= 4
F(x) = -9x^2 - 7x + 8
f(5) = -9(5^2) - 7(5) + 8
f(5) = -9(25) - 35 + 8
f(5) = - 225 - 35 + 8
f(50 = - 252 <==
Answer:
The candidate should get 5829 votes.
Step-by-step explanation:
This is a proportion question. The ratio should hold for both the pole and the actual vote.
Equation
x /9570 = 67/110 Multiply both sides by 9570
x = 67 * 9570 / 110 Multiply the two numerators.
x = 641190 / 110 Divide by 110
x = 5829
