X^2-9x=-8
x^2-9x+8=-8+8
x^2-9x+8=0
(x-8)(x-1)=0
x-8=0
x-8+8=0+8
x=8
x-1=0
x-1+1=0+1
x=1
There are 2 solutions, which are 1 and 8
Hello here is a solution :
<span>h(g(f(x))) ?
</span>g(f(x))= g(2x+5)=(2x+5)²=(2x)²+2(2x)(5)+5² = 4x²+20x+25
h(g(f(x)))(x) = h(4x²+20x+25) = -2(4x²+20x+25)
h(g(f(x)))(x) = -8x²-40x-50
Answer: 1/12
Hope that helps :)
Steps:
Find the 2D area of the two triangles:
- multiply 6 x 8 and divide it by 2 (this is the bottom triangle.)
** don't use 10 because it is the hypotenuse.
- 6 x 8 = 48
- 48 / 2 = 24 (you will need to use this twice since there are 2 triangles)
Now find the 2D area of the three rectangles
- first you have to convert 4 yd to feet.
**1 yd = 3 ft
~4 yd = 12 ft
-now multiply 12 x 10
- 12 x 10 = 120ft (use this 3 times since there are 3 rectangles)
Now add all those together:
120 + 120 + 120 + 24 + 24 = 408
Answer:
4x -4 24
Step-by-step explanation:
Remember distribution, 4 × x then 4 x -6
