the length of the rectangle is 10ft
Step-by-step explanation:
let the length = x
width = x - 4
area = length X width
so, according to the problem
x(x-4) = 60
or,
- 4x = 60
or,
-4x -60 = 0
or,
- 10x + 6x -60 = 0
or, x(x-10) +6(x-10) =0
or, (x-10)(x+6) = 0
x = 10 ( x= -6 for length this value is not possible)
so length is 10ft
width = 10 - 4 = 6ft
Answer:
2x+14+6y
Step-by-step explanation:
You could see the pattern
it cost 3.8 cent to print 1 dollar,
It cost 2 x 3.8 cents to print 2 dollar
it cost 3 x 3.8 cents to print 3 dollar
First equation
f(x) = 3.8 x
Same with second equation,
f(x) = 15x
for equation 3, it would be :
y = 1.50 x - 0.8x
Hope this helps
Answer:
Its a right isosceles triangle
Answer:
the answer would be 38 :)
Step-by-step explanation:
24÷3=8
(8)+3+3 to the 3rd power
3×3×3=27
8+3=12 ->12+27=38
hopefully this helps :)
