I know it’s A. But not sure about the fraction part I’ll solve it later for you
If it's double the original area it's 2(x^2)
this means the area of Mary's new garden is 2x^2
You need to find the area of the the whole rectangle (including white region inside of it). Then subtract the white region from the whole area to get the area of the shaded region.
The area of the whole rectangle is
(9x - 2)(2x + 7)
= 18x^2 + 63x - 4x - 14
= 18x^2 + 59
The area of the white (unshaded) region is
3x(x + 12)
= 3x^2 + 36x
The area of the shaded region will be the area of the whole rectangle minus the area of the white region inside it.
(Area of whole rectangle) - (Area of unshaded region)
= (18x^2 + 59) - (3x^2 + 36x)
= 18x^2 + 59 - 3x^2 - 36x
= 15x^2 - 36x + 59
Answer:
x=0.5×1±√33
Step-by-step explanation:
x+8=x² and 2(x+8)=2x²
x²-x-8=0
Answer:
$18
Step-by-step explanation:
15*2=30
So we need to multiply 9.00 by 2 too!
9*2=18
Keep up the good work!
