Answer: 6928
----------------------------------------------------------
Explanation:
We have two areas we need to find: The area of the trapezoid and the area of the rectangle. Let's call these areas A1 and A2.
Area of Trapezoid = (height)*(base1+base2)/2
A1 = h*(b1+b2)/2
A1 = 80*(150+100)/2
A1 = 80*250/2
A1 = 20000
A1 = 10000
Area of Rectangle = (length)*(width)
A2 = L*W
A2 = 48*64
A2 = 3072
Subtract the two areas (A1-A2) to get the difference D
D = A1 - A2
D = 10000 - 3072
D = 6928
This difference D is exactly equal to the shaded area.
Find the lengths AB, BC and AC.
length AB= √(4²+(-4)²) = √32
length BC = √(4²+7²) = √65
length AC = √(8²+3²) = √73
From the lengths of this triangle it can be seen that no side is equal to the other and also it is not a right triangle.
So, triangle ABC is a scalene.
Answer:
18. 2 times a number p squared
19. 3 times a number m to the power of 5
20. 1/2 plus 2
Step-by-step explanation:
Complimentary angles add up to 90 degrees and supplementary angles add up to 180 degrees...
Complementary angle = 90-52= 38°
Supplementary angle = 180-52= 128°
Answer:
Step-by-step explanation:
f(x)=2(x+4)(x-1)
=(2x+8)(x-1)
<h3>=2x²-2x+8x-8</h3>
=2x²+6x-8
