<span>X^3 + 2x^2 + x + 2
=x^2(x+2) + (x+2)
=(x+2)(x^2 +1)

In this situation you would use cos
which is adjacent over hypotenuse
so I take the cos50 and have it equal to 17 / x
cos(50)= 17/x
which is the same as ...
17 divided by cos(50) =x
x=26.44730506
which rounds to 26.45
So your answer would be A)
I hope everything makes sense, enjoy! <span />
Answer:
Step-by-step explanation:
x^2 - x - 35
This is prime
- cannot be factored
Height of a trapezoid:
h = 5 · sin 80° = 5 · 0.985 = 4.924
x = 5 · cos 80° = 5 · 0.17365 = 0.868
7 - x = 7 - 0.868 = 6.132
By the Pythagorean theorem:
d² = 6.132² + 4.924²
d² = 37.6 + 24.25
d² = 61.85
d = √61.85
d = 7.86 ≈ 8
Answer: The length of a diagonal brace is 8 feet.
Answer:
Only one solution
x=1/2
Step-by-step explanation:
Collect like terms.
3/2x=3
Solve for x.
6x=3
