Answer:
x = {2, 6}
Step-by-step explanation:
f(x) = 2x^2 - 14x + 24
Factor
(2x - 12)(x - 2) = 0
2x - 12 = 0
2x = 12
x = 6
x - 2 = 0
x = 2
x = {2, 6}
Answer:
11
Step-by-step explanation:
x + 2y = 24.....x = 24 - 2y
now sub 24 - 2y in for x, back into the other equation
2x + y = 9
2(24 -2y) + y = 9
48 - 4y + y = 9
-4y + y = 9 - 48
-3y = - 39
y = -39/-3
y = 13
x + 2y = 24
x + 2(13) = 24
x + 26 = 24
x = 24 - 26
x = -2
so the value of x + y = -2 + 13 = 11 <===

Answer:
512
Step-by-step explanation:
first you would write it with the other numbers it gives which should look like this: 4+(7-5) then you do the part that is in parentheses 7-5=2 then 4x4x4x4 which equals 256 then you multiply the two together and you should end up with 512
