-3-10= -13
Use the keep, change, opposite method.
Keep -3, change minus to add, and the opposite of 10 is -10.
-3 + (-10) = -13
You are basically adding negatives together if you use my method.
I hope this helps :)

-3 is 3 less than zero. So when you also take ten away, the -3 becomes -13

Find fog(x) when f(x) = 2x² + x and g(x) = 3x + 2
nekit [7.7K]
For fog or f(g(x)), plug g(x) into f(x):

2(3x+2)²+x

Then simplify:

2( (3x+2)(3x+2) )+x

2( 9x²+12x+4 )+x

18x²+24x+8 +x

18x²+25x+8

Then you can simplify this further using factoring methods to:

(2x+1)(9x+8)

Hope this helps!! :)

prohojiy [21]
First, we have to calculate the remaining amount of money after the cost of the ticket. It is 200 - 87.96 = 112.04 Dividing this number to 30, we can find the maximum number of t-shirts she can buy. It is less 4 and more than 3. So that, the final answer is 3.
