Answer:
x sqrt(7) - 49sqrt(x)
Step-by-step explanation:
sqrt(7x) [ sqrt(x) - 7sqrt(7)]
Distribute
sqrt(7x) *sqrt(x) - sqrt(7x)*7sqrt(7)
We know that sqrt(a) sqrt(b)= sqrt(ab)
sqrt(7x^2) - 7sqrt(7^2 *x)
Now lets separate out the perfect squares
sqrt(7) *sqrt(x^2) - 7sqrt(7^2)*sqrt(x)
x sqrt(7) - 7*7sqrt(x)
x sqrt(7) - 49sqrt(x)
Step-by-step explanation:
40 increases to 56.
<u>To find the percent increase:</u>
Subtract the increased value from the original value.
Divide the difference by the original value.
Multiply the quotient by 100 to represent the percent.
<u>Solve:</u>
There's a 40% increase.

Answer:
182
Step-by-step explanation:
The correct answer is 182 because to figure out the total we needed to multiply the 2 sides, a quicker way instead of counting. To do this you needed to multiply 13 times 14 and you would get 182!
Hope this helped!
