Answer:
A
Step-by-step explanation:
(2x^2 + 3x - 4) (x + 4)
FOIL.
2x^2 times x = 2x^3
3x times x is 3x^2
-4 times x = -4x
2x^2 times 4 = 8x^2
3x times 4 = 12 x
-4 times 4 = -16
Combine like terms to get 2x^3 + 11x^2 + 8x - 16.

Answer:
<h2>x = 30°</h2>
Step-by-step explanation:
Since the figure above is a triangle, all it's angles sum up to 180°
To find x , add up all the angles and subtract them from 180°
That's
57 + 93 + x = 180
150 + x = 180
x = 180 - 50
We have the final answer as
<h3>x = 30°</h3>
