7(3x-2)+4(x+5)
= 7*(3x)-7*2+4x+4*5 (distributive property)
= 21x -14 +4x +20
= 25x +6
Final answer: 25x+6.
Hope this helps~

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
Given x = adjacent
10 = hypothenuse
Sohcahtoa (cah)
Cosine uses both adjacent and hypothenuse
x/10 = cos(37)
0.79863551 = x/10
x = 7.9763551
Solution: x = 8
