Answer:
x^2 +9x +1
Step-by-step explanation:
(5x-2+3x^2)+(4x+3)
Writing in decreasing order so we can combine like terms
3x^2 +5x+4x-2+3
Add and subtract like terms
3x^2 +9x +1
Answer:
V = 4 2/3 units ^3
Step-by-step explanation:
We are given the area of the back rectangle
V = BH where B is the area of the base
V = 3 1/3 * 1 2/5
Rewriting the mixed numbers as improper fractions
V = 10/3 * 7/5
V = 70/15
Simplifying
V = 14/3
Changing back to a mixed number
V = 4 2/3 units ^3
Answer:
8=58.5 9=125 10=55
Step-by-step explanation:
a triangle equals 180. so by add the angles we do know than subtracting the answer from 180. is our final answer
Answer:
96 units²
Step-by-step explanation:
This is because the triangle on the right can be transfer to the left. See picture beneath.
Then, since it makes a rectangle, 8 x 12 = 96. This is the answer: 96.
