The total surface area of the cylinder would be 748 sq inches. I have attached a picture of the work in case you need it. I hope this helps. :)
Answer:
(- 1, - 5 )
Step-by-step explanation:
Given the 2 equations
y = 3x - 2 → (1)
6 + y = - x → (2)
Substitute y = 3x - 2 into (2)
6 + 3x - 2 = - x
4 + 3x = - x ( add x to both sides )
4 + 4x = 0 ( subtract 4 from both sides )
4x = - 4 ( divide both sides by 4 )
x = - 1
Substitute x = - 1 into (1) for corresponding value of y
y = 3(- 1) - 2 = - 3 - 2 = - 5
solution is (- 1, - 5 )
x^2 - 2x + 2
x = 1 + i
(1 + i)^2 - 2(1 + i) + 2
<em><u>Distributive property.</u></em>
(1 + i)(1 + i) - 2 - 2i + 2
<em><u>Continue distributive property on left side.</u></em>
1 + i + i + i^2 - 2 - 2i + 2
<em><u>Combine like terms.</u></em>
1 + 2i + i^2 - 2 - 2i + 2
1 + i^2
<em><u>i^2 can be interpreted as -1.</u></em>
1 - 1 = 0
The expression is equal to 0.
It might be -0.35, -0.3, 0.5, and 0.55
