11. Area as product = 7( d + 4 )
Area as sum = 7d + 28
12. Area as product = y( y + 3 )
Area as sum = y^2 + 3y
13. In circles , 12x and 60
Area as product = 12 ( x + 5 )
Area as sum = 12x + 60
14. In circles , x and 4
Area as product = 5 ( x + 4 )
Area as sum = 5x + 20
Hope this helps :)
The answer is 11.4% where 2500-11.4%=2215.
X = cost of 1 sweat shirt
3x = 45
x = 15
5x = 5(15) = 75
It would cost $75. Hope this helps!
