Area = 1/2 x B x H
1/2 x 28.3 x 12.8 = 181.12
Answer is #3
<span>The ratio of the measures of the sides of a triangle is 5:7:8, and its perimeter is 40 inches. what is the measures of each side of the triangle
Sides are (5/20) x 40 = 10 inches
(7/20) x 40 = 14 inches, and (8/20) x 40 = 16 inches respectively. </span>
A shape that has both 4 right angles AND 4 sides of equal length is a square.
Answer:
r= 0
Step-by-step explanation:
Cancel equal terms on both sides of the equation:
= 3r - 5r = -4r
collect like terms
= -2r = -4r
move variable to left and change its sign
= -2r + 4r = 0
collect like terms
= 2r = 0
divide both sides of the equation by 2
r=0
