Answer:
20 inches x 26 inches
Step-by-step explanation:
set up an equation: (2x)(x+7)=520
now just solve it
2x^2+14x=520
x^2+7x-260 = 0
factor: (x-13)(x+20)
x = 13 and -20
13 is the only one that works because you can't have a negative side length
13+7=20
13*2=26
lmk if you don't understand how to solve that equation
Answer:
195
Step-by-step explanation:
Let wining name have, x votes
1st = x
2nd = x - 53
3rd = x - 79
4th = x - 105
x + (x - 53) + (x - 79) + (x - 105) = 963
x + x - 53 + x - 79 + x - 105 = 963
4x - 237 = 963
4x = 963 + 237
4x = 1200
x = 1200 / 4
x = 300
4th = x - 105
x - 105 = 300 - 105 = 195
