Can't understand anything!
Answer: (5, 2)
We simply add up the corresponding coordinates. The x coordinates of the two vectors are 2 and 3. They add to 2+3 = 5
The y coordinates are -1 and 3. They add to -1+3 = 2
So overall,
(2,-1) + (3,3) = (2+3, -1+3) = (5,2)
is the answer
Answer:
85,1 ft^2
Step-by-step explanation:
Semicircle area : 4^2π / 2 = 8π = 25,1 ft^2
Triangle area : (8 x 15) / 2 = 60 ft^2
Total Area = 60 + 25,1 = 85,1 ft^2
I think it's not, because for proportion, you use the given clues to solve for a value or an unknown number.

2+3i
------ should be multiplied (numerator and denominator both) by 2+i. This will
2-i remove i from the denominator.
(2+3i) 2+i 4 + 2i + 6i - 3 1 + 8i
-------- * ----------- = ---------------------- = ---------- (answer)
2-i 2+i 4+(-1) 8
You could also write this as (1/8) + i.
