Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 4 - x²
g(x) = 2x + 5
<u>Step 2: Find g(-2)</u>
- Substitute in <em>x</em> [Function g(x)]: g(-2) = 2(-2) + 5
- Multiply: g(-2) = -4 + 5
- Add: g(-2) = 1
<u>Step 3: Find f(g(-2))</u>
- Substitute in <em>x</em> [Function f(x)]: f(g(-2)) = 4 - (1)²
- Evaluate exponents: f(g(-2)) = 4 - 1
- Subtract: f(g(-2)) = 3
Red shirts and blue shirts equally count to his bonus, so he has 15 + 23 = 38 shirts sold at this moment. He needs to sell 75 shirts for the bonus. We subtract our goal from what he have; 75 - 38 = 37.
The strategy here: subtract the goal (75 shirts) from what you did to get to the goal (15 shirts and 23 shirts).
Nathan needs to sell 37 more shirts for the bonus. Hope this helps.

Answer:
2n - 1
Step-by-step explanation:
you add the 2 <em>ns to get 2n then you add the 1 to the equation to make </em>
<em> </em><em>2n - 1</em>
It says the sum, which hints that the two numbers will be added
So we can start the equation with 10+(1/3n)
we are then told they add up to 25
So they will equal 25
So the equation is
10+(1/3n)=25
