Answer:
270 centimeters squared
Step-by-step explanation:
A = H x W / 2
A = 18 x 30
A = 270

Answer:
P = x³ − 9x² + 36x − 54
Step-by-step explanation:
Complex roots come in conjugate pairs. So if 3−3i is a zero, then 3+3i is also a zero.
P = (x − 3) (x − (3−3i)) (x − (3+3i))
P = (x − 3) (x − 3 + 3i) (x − 3 − 3i)
P = (x − 3) ((x − 3)² − (3i)²)
P = (x − 3) ((x − 3)² + 9)
P = (x − 3)³ + 9 (x − 3)
P = x³ − 9x² + 27x − 27 + 9x − 27
P = x³ − 9x² + 36x − 54
Answer:
x =25
Step-by-step explanation:
<M + <R = 180
We know M = 5x+10 R = 45
Substituting these values in
5x+10 + 45 = 180
Combine like terms
5x+55 = 180
Subtract 55 from each side
5x+55-55 = 180 -55
5x = 125
Divide each side by 5
5x/5 = 125/5
x = 25
