Answer:
8(3y + 2) = 8 * 3y + 8 * 2 = 24y + 16
Step-by-step explanation:
The outer rectangle has width 8 and length 3y + 2.
The area of the outer rectangle is length times width or width times length, so the area is 8(3y + 2).
We can also find the area by finding the area of each small rectangle, and adding the areas together.
The left small rectangle has dimensions 8 and 3y.
A1 = WL = 8 * 3y = 24y
The right small rectangle has dimensions 8 and 2.
A2 = WL = 8 * 2 = 16
The total area of both small rectangles is 24y + 16
That tells use that
8(3y + 2) = 8 * 3y + 8 * 2 = 24y + 16
This is the distributive property at work.
Answer:
b=√3
a=2
Step-by-step explanation:
Since you are given one side and an angle, you can immediately think of using cos, sin, and tan
When solving for b, you would set up your equation with tan30=1/b since tangent is opposite/adjacent
Next for a, you would solve for sin30=1/a since sine is opposite/hypotenuse
