I would say C since a and d don't match, so either c or d

PLEASE HELP ME ASAP!!! The diagonal of Andres rectangular TV screen is 39 in. The width of his TV screen is 34 inches. which mea
Y_Kistochka [10]
You can use the Pythagorean theorem to answer this. The diagonal is the hypotenuse of the right triangle that is formed. So, your equation will look like (h is height):
34^2+h^2 = 39^2

We have to solve for h:
h^2 = 39^2-34^2
h =  \sqrt{39^2-34^2}

You can plug it into a calculator, and you get approximately 19.105. The answer closest to that is B. So, that's your answer! Hope it helps. If anything doesn't make sense, hmu!

Rewrite the function y= x^2 + 14x + 4 in vertex form
Step2247 [10]
Vertex form is basically commplete the square
y=a(x-h)^2+k


y=x^2+14x+4
take 1/2 of 14 and square it, (7^2=49)
add that and its negative to right side
y=x^2+14x+49-49+4
factor perfect squaer
y=(x+7)^2-49+4
y=(x+7)^2-45

answer is A

Not sure what form you want this in:

Simplified this is 4x+4y

Factorised this is 4(x+y)
