Here is the correct answer of the given polynomial above. The answer is [(-3x^2)+(-8x^2)]+4x+[9+5]. The expression that can be used to find the sum of the polynomials given above is [(-3x^2)+(-8x^2)]+4x+[9+5].
Break it up into two rectangular solids. like two legos stuck together.
top is 10x4x3 = 120
bottom is 2x4x4 = 36
combined 120+36=156 ft²
The first 4 is forty, the second 4 is four. Both of them together are fortyfour (44)
Answer:
19°
Step-by-step explanation:
m<A + m<B + m<C = 180°
a + 17° + 49° + 5a = 180°
6a + 66° = 180°
6a = 114°
a = 19°
