The answer is D) 625 cm^3
So what we're doing is subtracting g(x) from f(x). If f(x) = -8x^2 - 5x, and g(x) = 17x^2 + 11x, we're just subtracting two binomials.
(- 8x^2 - 5x) - (17x^2 + 11x) Is our problem. If you don't know how to subtract polynomials, I'll show you step by step.
First you want to distribute the implied ones to get rid of the parenthesis. This means that you multiply the first set of numbers by 1, and the second by -1. The first set will stay the same, but when you multiply the second set by -1, both terms will become negative.
(- 8x^2 - 5x) - (17x^2 + 11x)
1(- 8x^2 - 5x) - 1(17x^2 + 11x)
-8x^2 - 5x - 17x^2 - 11x.
Now, we want to add/subtract like terms. Like terms are terms with the same variable and exponent. All we do is add/subtract the coefficient. The variable and exponent will stay the same. If a term does not a show a coefficient, then the coefficient is 1.
-8x^2 and -17x^2 are like terms. Subtract the coefficients.
-8 - 17 = -25
-8x^2 - 17x^2 = -25x^2
-5x - 11x
-5 - 11 = -6
-5x - 11x = -6x
So our final result is -25x^2 - 6x.
Hope this helps!!

Probability of the next six babies being a girl = (0.4810)^6 = 0.0124
Therefore probability of at least one boy in next six births = 1 - 0.0124
= 0.9876 Answer
Obtuse, acute, and right.
Answer:
124858
Step-by-step explanation:
The first 4 digits are simple, you multiply the first digit of the equation by the 2nd digit and then for the other 2 you multiply the first digit of the equation by the 3rd digit.
6 + 2 + 8
6 * 2 = 12
6 * 8 = 48
Then the last 2 digits are the sum of the products of the 1 and 2 and 1 and 3 and subtract it by the 2
12 + 48 = 60
60 - 2 = 58
Put them together
