<span>The answer two this question is C.
You can get this answer by multiplying the two polynomials and then simplifying. See the steps below:
(4x^2 - 5)(x + 3) ---> Now multiply the two parenthesis.
4x^3 - 5x + 12x^2 - 15 ---> Arrange the numbers by decreasing exponents.
4x^3 + 12x^2 - 5x - 15
No simplifying can be done since there are no like terms. </span>
Divide 37.95 by 11 to get 3.45
so the answer is:
$3.45 per gallon
0.078 rounded to the nearest hundredth is 0.08
Answer:
39 ft^2
Step-by-step explanation:
Find the area of the triangle and subtract the area of the square.
area of triangle = bh/2
area of square = s^2
shaded area = bh/2 - s^2
shaded area = (20 ft)(16 ft)/2 - (11 ft)^2
shaded area = 160 ft^2 - 121 ft^2
shaded area = 39 ft^2
R = 30 because r = 1,5,10,25
30/5+1=7
6+1=7
