Step-by-step explanation:
<u><em>The correct equation is</em></u>

solve for x
Multiply by 8 both sides to remove the fraction

subtract 15 both sides

divide by 8 both sides


Answer:
<em>First.</em> Let us prove that the sum of three consecutive integers is divisible by 3.
Three consecutive integers can be written as k, k+1, k+2. Then, if we denote their sum as n:
n = k+(k+1)+(k+2) = 3k+3 = 3(k+1).
So, n can be written as 3 times another integer, thus n is divisible by 3.
<em>Second. </em>Let us prove that any number divisible by 3 can be written as the sum of three consecutive integers.
Assume that n is divisible by 3. The above proof suggest that we write it as
n=3(k+1)=3k+3=k + k + k +1+2 = k + (k+1) + (k+2).
As k, k+1, k+2 are three consecutive integers, we have completed our goal.
Step-by-step explanation:
By the Pythagorean theorem
.. x = √((2√3)^2 -(√6)^2) = √(12 -6) = √6 . . . . cm
x = √6 cm
Answer:
125%
Step-by-step explanation:
so you are increasing by $10, and $10 is 25% of $40, so the percent change is 125%
For the square area we have:
12.12=144
and for the rectangle we have:
4.11=44
