What is h(x) = 7 + 10x + x2 written in vertex form?
O h(x) = (x - 25)2 - 18
O h(x) = (x – 5)2 + 32
O h(x) = (x + 5)2 – 18
O h(x) = (x + 25)2 + 32
and

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

i think da answer is

d.square root of 3
