Answer:
in steps
Step-by-step explanation:
upper square: P = 20x² + 8
<u>side: P/4 = 5x² + 2</u>
<u>A = side² = (5x² + 2)² = 25x⁴ + 20x² + 4</u>
Middle equilateral Triangle: A = x² + 4x + 4 base = 2x + 4
A = base x height / 2
(x + 2)² = 2 (x + 2) x height /2
<u>height = x + 2</u>
<u>perimeter = 2 (x + 2) x 3 = 6x + 12</u>
Lower trapezoid: A₁ = 2x² + 24x + 40 = 2 (x² + 12x + 20) = 2 (x + 2) (x + 10)
A₁ = (x + 10)² = 2 (x + 2) (x + 10)
x + 10 = 2x + 4
x = 6
<u>A₂ = (2x + 4) (x + 10) / 2 = (16 x 16) / 2 = 128</u>
A₁ = (6 + 10)² = 256
<u>AT = 256 + 128 = 384</u>
Answer:
B. 9 - i
Step-by-step explanation:
Combine the real and imaginary parts in numbers 12 - 5i and -3 + 4i
(12 + 5i) + (-3 + 4i)
12 - 3 + (-5 + 4)i
Add 12 to -3. Add -5 to 4.
9 + (-i)
9 - i
05.05)On a coordinate plane, the coordinates of vertices R and T for a polygon are R(−6, 2) and T(1, 2).
Answer:
40 % increase
Step-by-step explanation:
New price - original price
42-30 = 12
Divide by original price
12/30 = .4
Change to a percent
.4 * 100
40%
40 % increase
