Answer:
2(x+5)
Step-by-step explanation:
Whatever is inside of the ( ), simply plug that digit into the x-values for f(x)
So: f(x) = 7x - x^2, and f(7+h) - f(7)
= [7(7+h) - (7+h)^2] - [7(7) - (7)^2]
= [49+7h - 49+14h+h^2] - [49-49]
= 49-49 + 7h+14h + h^2 = h^2 + 21h =
h (h+21), h (h+21) = 0
h=0... But it stated h cannot = 0
So h+21 = 0, h = -21

Answer:
x = 5
Step-by-step explanation:
In a parallelogram, the diagonals bisect each other. This means ...
PQ = PS
2x +15 = 5x
15 = 3x . . . . . . subtract 2x
5 = x . . . . . . . divide by 3
<span>34 12/27-19 5/6
</span>You may get common denominators.
12*2 = 24
27*2 = 54
5*9=45
6*9 = 54
34 24/54 - 19 45/54
Subtract 19.
15 24/54 - 45/54
14 33/54 = Answer.
Answer:
8x- 38
Step-by-step explanation:
3(x-6)+5(x-4)
Distribute
3x- 18+5x -20
Combine like terms
3x+5x -18-20
8x- 38
