What I did was 27.99-21.59 which equals 6.40 and then times that by 12 which brings you to 76.80
Answer:
C
Step-by-step explanation:
To factor x^2+8x+16, you have to find two numbers that add up to 8 and multiply to your constant, 16. 4 and 4 fit these requirements so you can factor them as (x+4)(x+4). Hope I explained it okay :)
Volume of jupiter: 1.43×10^15cubic kilometers
volume of earth: 1.08×10^12 cubic kilometers
In the expression 4 to the power of 9, the number 9 is called the D. exponent.
Number four here is the base, and the exponent is always shown as a superscript to the right of the base. It shows how many times you are supposed to multiply the base by itself.
Answer:
x ≈ - 10.65, x ≈ - 5.35
Step-by-step explanation:
Given
(x + 8)² - 7 = 0 ( add 7 to both sides )
(x + 8)² = 7 ( take the square root of both sides )
x + 8 = ± 
( subtract 8 from both sides )
x = - 8 ± , thus
x = - 8 - ≈ - 10.65
x = - 8 + ≈ - 5.35
