I don’t really need to you can come to my
Just add up all the sides
10 + 10 + 4 + 4 = 28
Hope that helps

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 1 - x
g(x) = x² + 2x - 5
(f + g)(x) is f(x) + g(x)
<u>Step 2: Solve</u>
- Substitute in functions: (f + g)(x) = (1 - x) + (x² + 2x - 5)
- Combine like terms (x): (f + g)(x) = x² + x - 5 + 1
- Combine like terms: (f + g)(x) = x² + x - 4
Answer:
40 miles
Step-by-step explanation:
let distance be d and time be t
Since d varies directly with t, then the equation relating them is
d = kt ← k is the constant of variation
To find k use the condition d = 75 when t = 3
k = 
= 
= 25
d = 25t ← equation of variation
when t = 1.6, then
d = 25 × 1.6 = 40 miles
