10 ???? im Guessing.. Hope Its Right (: pretty sure it is ..
3/4(8p+12)+3/8(16p-8)
=3/4[(8p+12)+1/2(16p-8)]
=3/4[8p+12+8p-4]
=3/4[16p+8]
=3/4*8*[2p+1]
=6[2p+1]
=12p+6
7,000lbs x 1=3.5 tons. 3.5 tons is 7,000lbs.
Your answer would be, Yes! It is an Isosceles Trapezoid, Because, Isosceles trapezoids have at least one set of opposite sides, that are parallel, mainly the base, and it's opposite. The non-base sides are equal in length to each other, and the base angles are equal to each other.
Hope that helps!!!!!!
Answer:
Those areas are: A 1 = 12, A 2 = 19
Step-by-step explanation:
The area of shape 1 : it consists of 1 square + 4 right triangles
Area of the square: A = a², area of the triangle: A = 1/2 · a · h
A 1 = 2² + 4 · 1/2 · 2 · 2 = 4 + 8 = 12
The area of shape 2 : it consists of 2 isosceles triangles
A 2 = 1/2 · 2 · 4 + 1/2 · 6 · 5 = 4 + 15 = 19
