Answer:
1) x²+4x=2700
2) 50x50
Step-by-step explanation:
Pony area = x²
line-up area=4x
x²+4x=2700
x²+4x-2700=0
(x-50)(x+54)
So x= 50 or -54. Since it can’t be a negative number, it must be 50.
CHECK:
Square = 50x50 = 2500
Line up area = 50x4 = 200
2500+200=2700 YES
$6.24. This is because 1.44 / 6 = 0.24, and 0.24 x 26 = 6.24.
Answer:
the area is 68 feet
Step-by-step explanation:
-first pretend that one spot is filled and if you do that the whole rectangle is 8 by 10.
- the area of something is length times width and so 8 times 10 is 80
- however, we can't pretend that we don't have a hole anymore so to figure out that tiny rectangles area we have to find its width and length which is 4 and 3.
- 4 times 3 is 12 and since we have that we subtract 12 from 80 and we get 68.
