Please help i need to finish this!!
s2008m [1.1K]

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

HELP PLEASE! whats the height and base??
ddd [48]

Answer: 7.5

Step-by-step explanation:

Area of the bottom left triangle = 4x3/2 = 6

Bottom right = 6x3/2 = 9

Top right = 3x4/2 = 6

Top left = 6x3/2 = 9

6+9+6+9 = 30

Each square unit is 4

So the answer should be 30/4 = 7.5

Hope this is correct
