Answer:
7.7u - 5.1v + 14.5w
Step-by-step explanation:
Given length:
Side A = (1.2u+1.8v) centimeters,
Side B = (6.5u+8.7w) centimeters
Side C = (5.8w-6.9v) centimeters
Perimeter of a triangle = side A + side B + side C
= (1.2u+1.8v) + (6.5u+8.7w) + (5.8w-6.9v)
= 1.2u + 1.8v + 6.5u + 8.7w + 5.8w - 6.9v
Collect like terms
= 1.2u + 6.5u + 1.8v - 6.9v + 8.7w + 5.8w
= 7.7u - 5.1v + 14.5w
Therefore, the perimeter of the triangle is 7.7u - 5.1v + 14.5w
Answer:Understand the volume of a rectangle equals it's length x width x height. If your box is a rectangular prism or a cube, the only information you need is the box's length, width, and height. You can then multiply them together to get volume. This formula is often abbreviated as V = l x w x h.

Answer:
C. 189
Step-by-step explanation:
Each triangle is 27 which makes it 108, and 108+81=189
Answer:
A =90 in^2
Step-by-step explanation:
The area of the rhombus is found by
A = 1/2 d1 * d2 where d1 and d2 are the diagonal lengths
d1 = 2*6 =12
d2 = 2 *7.5=15
A = 1/2 (12*15)
A =90 in^2
