If the original quantity is 10 and the new quantity is 11, what is the percent crease?
LenKa [72]

Answer:

10 %

Step-by-step explanation:

We first find change in the quantities

Then we write the change in quantity on original quantity and multiply by 100%

This implies that,

\frac{11 - 10}{10} \times 100\%

=\frac{1}{10}\times100\%

=10\%

What is the value of 7x 2squared + 2x when x = 3?
mash [69]

Answer:

Given expression has the value 69

Step-by-step explanation:

Given equation is:

=7x^2 + 2x

Now we have to put x = 3

So the equation will become:

=7(3)^2 + 2(3)

By simplifying:

As 3^{2} = 9

and 2*3 = 6

So the above equation will become:

=7(9 ) + 6\\= 63 + 6\\= 69

So the value of given expression is 69.

i hope it will help you!
