Answer:
21x - 36
Step-by-step explanation:
that's just assuming that you only need to simplify the answer and not solve it.
Answer:
Length=12 inches Width=6 inches
Step-by-step explanation:
X can stand for the width. 2x can stand for the length since it is twice the width. The perimeter would then equal 6x. 6x is equal to 36. Divide by 6 to isolate x. X equals 6 inches. So twice the width would be 12 inches.
Answer:
Area = B x H + L (sum of sides of triangle)
= 9 x 12 + 10 (12 + 15 + 9)
= 108 + 360
=
Either your options are wrong or question is to find lateral surface.
Lateral Surface area = ( a + b + c) x H , where a, b , c are sides of the triangle.
Lateral Surface Area = (12 + 15 + 9) x 10
=
It’s gonna be radical 10x/ 4x.
