Answer:
6-11i
Step-by-step explanation:
(2 + 7i) - (6 + 8i) + (10 - 10i)
Distribute the minus sign
(2 + 7i) - 6 - 8i + (10 - 10i)
Combine like terms
2-6 +10 +7i-8i-10i
6 -11i
Make y the subject:
y = 6 - x
Now, use Elimination.
0 = 3x - 3
Divide both sides by 3:
0 = x - 1
So x = 1.
Substitute back into the equation:
y = 6 - (1)
So y = 5.
Hence, the answers are x = 1, y = 5.
The answer is A.) Length = 15, width = 9.
9x2 = 18, 18 - 3 = 15
15 x 2 = 30, 9 x 2 = 18
18 + 30 = 48.
