Answer:
x < -2
Step-by-step explanation:
The answer is D, 8$. One easy way to do it is to take 10% of 40, which is 4, and double it.
Number of sides= 10
Side length= 4.6 ( or in this case base)
161 sq inches / 10 = 16.1 area of triangle.
Area of triangle =(b<span>ase * </span>height)/2
16.1=(4.6*h)/2
multiply 16.1 by 2 (cancels the dividing the 2)
32.2=4.6*h
divid 32.2 by 4.6
<span>7 is the height of the triangle</span>
You can take out 2x^3 from both terms making it
2x^3 (15+8x^2)
Answer is B
16 - 7 is 9
9 x 2 is 18
His weekly allowance is 18
