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
Construction.
When construction workers need measurements that are fractions they need to be able to multiply/add/subtract/divide all of those different fractions and mixed numbers.
I hope I was able to help. Best of luck.
Answer:
y=5/2 - 3x/4
Step-by-step explanation:
Answer:
CHILDREN= 389
ADULT=310
Step-by-step explanation:
1) A + C = 710 2) A*2.50 + C*1.2 = 1288.75
OR, A= 710-C (710-C)*2.50 + C*1.2=1288.75
1775-2.50*C+1.25*C=1288.75
1775 -1.25*C = 1288.75
-1.25*C=1288.75-1775
1.25*C=486.25
C = 486.25/1.25
C = 389
Again or, A + C = 710
A = 710 - C
A = 710 - 389
A = 321
