Answer:
6 1.5/4
Step-by-step explanation:
Hank will need 2 gallons of gas. 85/5 is 17, so Hank can go 17 miles on 1 gallon of gas. 17•2= 34, to go 34 miles you will need 2 gallons of gas.
I’m guessing you just have to multiply all the sides together and divide
Answer:
(3x^2 - 1)(3x^2 + 1)(9x^4 + 1).
Step-by-step explanation:
Using the identity for the difference of 2 squares;
a^2 - b^2 = (a - b)(a + b)
we put a^2 = 81x^8 and b^2 = 1 giving
a = 9x^4 and b = 1, so:
81x^8 − 1 = (9x^4 - 1)(9x^4 + 1)
Applying the difference of 2 squares to 9x^4 - 1:
= (3x^2 - 1)(3x^2 + 1)(9x^4 + 1).

Answer:
f(x) = -4x² - 64x - 202
Step-by-step explanation:
We can simplify this quadratic function given in vertex form into standard form by simplifying the exponents and adding like terms.
f(x) = -4(x+7)^2 - 6
f(x) = -4(x^2 + 14x + 49) - 6
f(x) = -4x² - 64x - 196 - 6
f(x) = -4x² - 64x - 202
