Answer: (f·f)(0) = 4

(fof)(0) = -8

Step-by-step explanation:

f(x) = 3x - 2

(f·f)(x) = (3x - 2)(3x - 2)

= 9x² - 12x + 4

(f·f)(0) = 9(0)² - 12(0) + 4

= 4

(fof) = 3(3x - 2) - 2

= 9x - 8

(fof)(0) = 9(0) - 8

= -8

I wasn't sure if you wanted multiplication or composition so I solved both

Answer:

x = 2 and x = -3

Step-by-step explanation:

We need to find the value of x in the below expression.

$\sqrt{x+7} -1=x$

Adding 1 to both sides,

$\sqrt{x+7} -1+1=x+1\\\\\sqrt{x+7}=x+1$

Squaring both sides,

$x+7=(x+1)^2\\\\x+7=x^2+1+2x\\\\x^2+1+2x-x-7=0\\\\x^2+x-6=0\\\\x=2\ and\ -3$

Hence, this is the required solution.

Pls help i need this to get my grade up

Answer:

Step-by-step explanation:

So first I solved for y. The angle boc and cod together have to be 180 degrees so I subtracted 180 from 45 and then divided by 5. I got 27. Then since I knew what y was I could solve x. Since 5 times 27 is 135. I just plugged in 22 and 23 and realized it had to be 22.

RAISE THAT GRADE!! you got this I hope this helps!
