Answer:
2340 ft^2
Step-by-step explanation:
Assume the width to be...x
then the length to be....x + 7
Perimeter = 2(x)+ 2(x + 7)....lm multiplying by two because there is two sides(length and width)
;194 = 2x + 2x + 14
; x(width) = 45ft
then the Area = 45 × (45 + 7)
;AREA = 2340 ft^2
Answer:
<h2>x = 5.7</h2>
Step-by-step explanation:
To find x first cross multiply
We have
7x = 8 × 5
7x = 40
Divide both sides by 7
That's
x = 5.7142
We have the final answer as
<h3>x = 5.7 to the nearest tenth</h3>
Hope this helps you
Equilatral
equi-equal
lateral-side
sides have to be equal
therefor
4n=2n+10=7n-15
minus 2n from everybody
2n=10=5n-15
2n=10
divide 2
n=5
see if that works
10=5n-15
10=5(5)-15
10=25-15
10=10
true
n=5
