15i+15
Step-by-step explanation:
(6+3i)(3+i)
18+9i+6i+3i^2
18+15i+3(-1)
18+15i-3
15i+15
Answer: YES!
<u>Step-by-step explanation:</u>
Assuming ABCD is a parallelogram, the opposite sides are parallel
AB║DC and AD║ BC
The two angles are corresponding angles, which means they are equal to each other. Make them equal to each other in an equation.
11x - 2 = 130
Add 2 to both sides.
11x = 132
Divide both sides by 11.
x = 12
Perimeter = 2w + 2l
Since its a square, the length and width are equal therefore:
2(s + 3) + 2(s + 3) = Perimeter
You can simplify this into a variety of ways:
1. 4(s + 3)
2. 2s + 6 + 2s + 6
3. 4s + 12
