Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3x² + 2x
g(x) = 5x - 1
(f + g)(x) is f(x) + g(x)
<u>Step 2: Find</u>
- Substitute in functions: (f + g)(x) = 3x² + 2x + 5x - 1
- Combine like terms: (f + g)(x) = 3x² + 7x - 1
This triangle seems like A) Scalene Acute. Brainliest meeeee!
Answer:
Step-by-step explanation:
Distribute 4(x+2).
Subtract 2x and 8 from both sides.
Divide both sides of the equation by 2.
Answer:
the number of miles is 14,722
Step-by-step explanation:
The computation of the number of miles drive last year is shown below:
= Total cost ÷ cost per mile
= $1,560 + $3,740 ÷ $0.36 per mile
= $5,300 ÷ $0.36 per mile
= 14,722 miles
Hence, the number of miles is 14,722
Answer:
26.13716694
Step-by-step explanation:
the area of a semi cirlce is 1/2(π*r^2) so it was 14.13716694 and then you find the area of the triangle witch is H*B/2 and then add them 3 numbers together whitch is 6+6+14.13716694=26.13716694
