−3 (x+5 ) = 9.
-3(x) + -3(5) = 9
-3x -15 = 9
+15 +15
-3x = 24
/-3 -3
x = -8 Hope this helps!
Answer:
100/61 or 1.63934
Step-by-step explanation:
Given:
Length of the painting = 12 inches
Width of the painting = 10 inches
To find:
The area of the rectangular painting by using Distributive Property to decompose the factor 12.
Solution:
The area of a rectangle is

So, the area of the rectangular paining is

Using Distributive Property to decompose the factor 12, we get




Therefore, the area of the rectangular painting is 120 square inches.

C = 180 - (22 + 105) = 180 - 127 = 53 degrees
Area of triangle = 1/2 ab sin C
But a / sin A = b / sin B or a = b sin A / sin B = (14 x sin 22) / sin 105 = 5.429
Therefore, Area of triangle = 1/2 x 5.429 x 14 x sin 53 = 30.4 units^2
