(a-b)(a-b) = a^2 - 2ab + b^2

(2y-6)^2

= (2y-6)(2y-6)

= 4y^2 - 12y + 36

A wall is 300 square feet.a gallon of paint covers 110 square feet. What is an appropriate conversion factor to help determine h
saveliy_v [14]

Answer:

(1 gallon)/(100 ft^2)

Step-by-step explanation:

(1 gallon)/(100 ft^2) is a good conversion factor.  We could also use (100 ft^2)/(1 gallon), but I like the first, since the calculation is simpler:

(300ft^2)*/(1 gallon)/(100 ft^2) = 3 gallons  [I like multiplication better than division, and especially here, since 300/100 is 3, if my memory is correct.

Answer:

Mark me as brainlist

Step-by-step explanation:

Math Tutor or Teacher: amanpreet.jaggi

Hi,

Let width = w

Length = l

now according to the question

l = 3w+7

Perimeter = 2(w+l) = 462 .... equation 1

Substituting values of l and w in equation 1 we get

462 = 2(w+3w+7)

231 = 4w+7

224 = 4w

w = 56 yards

Now

l = 3w+7

l = 3*56+7

l=175 yards

So width = 56 yards and length = 175 yards

Aman

Find the greatest common divisor of 15,015 and 495
Reil [10]

ANSWER

The greatest common divisor of 15,015 and 495 is 165.


<u>EXPLANATION</u>

We use the Euclidean Algorithm to compute the Greatest Common Divisor as follows;

15015=30\times 495 +165


495=3\times 165 +0

The last remainder before zero is the greatest common divisor.


Therefore gcd(15015,495)=165
