3. 8(3+8)
Explanation : 8x3 = 24 + 8x8 =64 which is congruent to 24 +64
For the 8 inch pie you are paying about 55 cents per inch
for the 10 inch pie you are paying about 61 cents per inch
so the 8 inch pie is a better deal
hope this helped
oh and to get those numbers divide 4.39 by 8 and 6.15 by 10
The value of y = 40.
5x = 40
x = 8
180 = 40 + 40 + (2y + 20)
40 = y
<span>2x^3+3x^2-30x+7/x-3 divide</span>
-3 x + 1 > y
1/2x -1 (less than or equal to) y
