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:
A,D,E IS THE RATIOS EUQIVALENT TO8:5
Answer:
the area of the problem is 20
Answer:
Step-by-step explanation:
Ratio = 3 : 2
Length =3x
Width = 2x
Perimeter = 50 inches
2*(length + width ) = 50
2* (3x + 2x ) = 50
2* 5x = 50
10x = 50
x = 50/10
x = 5
Length = 3*5 = 15 inches
Width = 2*5 = 10 inches
