f(-2) = 2(-2)² - 8(-2) + 6 = 30
f(-1) = 2(-1)² - 8(-1) + 6 = 16
f(0) = 2(0)² - 8(0) + 6 = 6
f(1) = 2(1)² - 8(1) + 6 = 0
f(2) = 2(2)² - 8(2) + 6 = -2
-6q^2 + 4q^2 + 8q - 9a^2
Combine like terms:
-2q^2 + 8q - 9a^2
You cannot combine q^2 to q because they do not have the same number of exponents!
Answer : One of the numbers is 8. The other number is 17.
Step by step explanation :
X + x + 9 = 25
2x + 9 = 25
2x = 16
X = 8
So one of the numbers is 8, the other is 17 because 8 + 9 is 17. Please mark brainliest if possible ;)

Answer:
Step-by-step explanation:
Ratios exist because the constant of variation, k, is the same number multiplied into each side to keep them all proportionate to one another.
The question is basically asking us to find the value of k that not only keeps these sides in proportion to one another, but also has the perimeter come to 510. Because k is the same number and is our unknown, we can multiply each side by k and set the sum of the sides equal to 510.
3k + 6k + 8k = 510 and
17k = 510 so
k = 30
That means the lengths of 3(30) = 90, 6(30) = 180, and 8(30) = 240 are the lengths of the sides. 90 + 180 + 240 = 510
