First of all you'll have to
Factor x^2-4x+4 = (x-2)^2
Factor x^2+10x+25 = (x+5)^2
Factor x^2+3x-10 = (x+5)(x-2)
So you'll have (x-2)^2/(x+5)^2 X (x+5)/(x+5)(x-2)
Then cancel the (x-2) and (x+5) on both sides
Thus getting the answer of x-2/(x+5)^2
or x-2/x+10+25
7.14 mile per hour is how fast she ran
Answer:
Hey!
Your answer is C.42.4yd
Step-by-step explanation:
There are 2 ways you can work this on out...
1. Using Pythagoras Theorem...
= 30^2 + 30^2 = 1,800 (30^2=900 so you've added 2 of those to make 1,800)
= SQUARE ROOT THE ANSWER OF 1,800
= 42.42640687119285
TO GET A MORE PRECISE ANSWER WE ROUND IT UP TO 1 decimal place
= 42.4 yd is the diagonal length of the dance floor!!
HOPE THIS HELPS!!
Answer:
A. -16x²+64x+8
B. 72 ft.
Step-by-step explanation: A. Expand the perfect square binomial -16(x²-4x+4)+72, dist. -16 (-16x²+64x-64+72), then combine like terms (-16x²+64x+8)
B. Find the abs. max. by looking back at the vertex form. The max is (2,72). Use the y-value for the height.
