Answer: 15x^2+6x-20
Step-by-step explanation:
use symbolab.com for calculator and further steps
d/dx (5x+3)5
((x-2)(x+2))=2x
5(x-2)(x+2)+2x(5x+3)
15x^2=6x-20
<u><em>Hi there! </em></u>
<u><em>Answer:</em></u>
<u><em>X>1</em></u>
<u><em>*The answer must have a positive sign and greater than symbol.*</em></u>
Step-by-step explanation:
First, you subtract by 3 from both sides of an equation.

Then, you subtract by the numbers from left to right.


You can also divide by 2 from both sides of an equation.

Finally, you divide by the numbers from left to right.

<em><u>Final answer is x>1</u></em>
I hope this helps you!
Have a nice day! :)

Answer:
34 degrees and 131 degrees
Step-by-step explanation:
Complementary angles always add up to 90 degrees
90 - 56 = 34 degrees (1)
180 - 49 = 131 degrees (2)
Answer:
She can create a function for the total savings in terms of the time x by adding the two functions together. The new function should look like this:
T(x)=S(x)+a(x)
So now we can substitute the given functions:
T(x)=450+6(x-2)
But this function can be simplified for it to be easier for her to calculate her total amount of savings. We can do that by distributing the 6 into the parenthesis. This is, multiply the 6 by both the x and the -2, so we get:
T(x)=450+6x-12
and now we can combine like terms. We can subtract 12 from 450 so we get:
T(x)=6x+438
And that will be our final function.
