Plz me on this problem plz and you

y=4x^2-40x+107

Just distribute the equation.

y=4(x-5)^2+7

y=4(x^2-10x+25)+7

y=4x^2-40x+100+7

y=4x^2-40x+107

For this case we must change the following equation:

to the standard form:

By definition we have to:

Then, rewriting:

Applying distributive property to the terms within parentheses:

Finally we have:

answer: i think you should do the math and pay attention in class : )

step-by-step explanation:

that is truly what   think but if i get the answer i will

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
