2x^2+8xy+8y^2
2(x^2+4xy+4y^2)
You have to multiply 7 3/4 to 9.
First, turn 7 3/4 to an improper fraction which is 31/4.
Next, you multiply 31/4 to 9/1(same thing as 9) across from each other.
Then, you get the answer 279/4(31 x 9 = 279 ;4 x 1 = 4; 279/4).
Last divide 279 to 4 and get 67.75( .75 = 3/4 ; 69 3/4).
Answer:
<h2>B. 49,062.5 ft²</h2>
Step-by-step explanation:
The formula of an area of a circle:

r - radius
We have the diameter d = 250 ft. We know: d = 2r.
Therefore r = 250 : 2 = 125 ft.
Substitute:


To convert a decimal into a percentage, first we have to convert it into fractional form.
Because percentages are out of 100, the resulting fraction would be 3/100.
Next, to find the decimal, we would just divide the fraction (numerator divided by denominator).
3 % = 3/100 = 0.03
Money Required for making 1 Sandwich that is Cost Price of 1 Sandwich = S Dollar
Selling Price of 1 Sandwich = 20 % more than Cost Price S
= S + 20 % of S
= 
=$ 1.20 S
= $(S + 0.20 S)
Selling Price of 73 Sandwiches = $ 73 (S + 0.20 S)
The expression $73(S+0.2 S) →→ Selling Price of 73 Sandwiches
