What we are going to do is add
by
. The first thing we do is make common denominators for
and
:
. Now we add
by
:
. Now we make
a mixed number:
. Therefore, your answer is
. Hoped I helped. :)
You need the Pythagorean theorem to solve for the side lengths.
Shorter side:
sqrt(6^2+1^2)=sqrt(37)
Longer side:
sqrt(12^2+2^2)=sqrt(148)
Now multiply the sides together to get:
sqrt(37*148)=sqrt(5476)=74
Okay. So you can go 440 miles on 10 miles of gas. That’s 44 miles for 1 gallon of gas. For 60 miles of gas, you have to do 440 * 6. When you do that, your product should be 2,640. You can drive 2,640 miles on 69 gallons of gas and 44 miles per gallon of gas.
Answer:
Solution
Step-by-step explanation:
Rewrite logx729= 3 is an exponential form using the definition of a logarithm. If x and b are positive real numbers and b≠1, then logb(x)= y is equivalent to b^y = x.
X^3 = 729
Take cube root on both side and we get
x= 3√729
now we firstly simplify the 3√729
Rewrite 729 as 9^3
x = 3√9^3
pull terms out from under the redical, assuming positive real numbers
x=9
verify each of the solution by substituting them into logx729=3 and solving.
x= 9
