E and F
note that x² + 8x + 16 is a perfect square which factors as ( x + 4 )², thus
(x + 4 )² = 7 ( take the square root of both sides )
x + 4 = ± √7 ( note plus or minus )
subtract 4 from both sides )
x = ± √7 - 4
x = √7 - 4 → E
x = - √7 - 4 → F
You need to rewrite the first equation to solve for y to get y >1+3x
Then graphing the two equations, the bottom right becomes the correct answer.
Answer:
x =2
2 in, 6 in, 1 in

Answer:
Let's see what to do buddy...
Step-by-step explanation:
_________________________________
Step (1)
First we find the diameter ((h)) of the rectangle on the floor using the Pythagorean theorem.
So we have :

Step (2)
Now we another using of Pythagorean theorem for finding d :
_________________________________
And we're done.
Thanks for watching buddy good luck.
