Step-by-step explanation:
Open up equations and do FOIL method.
First equation:
(x + 2y)(x + 2y)
x^2 + 2xy + 2xy + 4y^2
Second equation:
(y + 2x)(y + 2x)
y^2 +2xy + 2xy + 4x^2

Step-by-step explanation:
This shape is called a rectangular prism. The formula for finding the volume of this prism is:
All you do is plug the values into the formula.
The length is 2m
The width is 1m
the height is 5m
Volume = (2m)(1m)(5m)
Volume =
Angles ∠ACD and ∠CAB are congruent because they are alternate angles. Then the area of the triangle AOB will be 22.53 square cm.
<h3>What is the area of the right-angle triangle?</h3>The area of the right-angle triangle is given as
A = 1/2 x B x H
Where B is the base and H is the height of the right triangle.
We know that angles ∠ACD and ∠CAB are congruent because they are alternate angles.
α₁ = 40°
AO = OC = 7.8 cm
Then the area of the triangle will be
Area = 1/2 x 7.8 x 7.8 x tan40°
Area = 22.53 square cm
