Answer:
x= 4, -1
Step-by-step explanation:
-2x - 2 + x^2 + x + 180 - 2x - 2 = 180
add like terms and put in descending order
x^2 - 3x + 176 = 180
subtract 180 from both sides
x^2 - 3x - 4 = 0
factor out the equation
(x-4)(x+1)=0
solve for x
x-4=0 x+1=0
x=4 x=-1
Answer:
f(x) = x³ + 10x² + 27x + 18
Step-by-step explanation:
Given the zeros x = - 3, x = - 6 and x = - 1
Then the factors are (x + 3), (x + 6), (x + 1)
and the polynomial is the product of the factors, that is
f(x) = (x + 3)(x + 6)(x + 1) ← expand the first 2 factors using FOIL
= (x² + 9x + 18)(x + 1) ← distribute
= x³ + 9x² + 18x + x² + 9x + 18 ← collect like terms
= x³ + 10x² + 27x + 18
B. 18x-54
9*2x= 18
9*(-6)=-54
Answer: Substances.
Step-by-step explanation:
Battery acid,
Coke,
Vinegar,
Blood,
Beer,
Soda,
Urine,
Saliva,
Eggs.
First, you plug in 3.50 for d. Then, you multiply 5 and 3.50 and get 17.50. After that, you subtract 17.50 from 42 , and you get 24.50. That means that Jamie will have $24.50 of her allowance left.
