Answer:
c = 2
Step-by-step explanation:
Substitute x = 1 + i into the equation
(1 + i)² - 2(1 + i) + c = 0 ← distribute left side
1 + 2i + i² - 2 - 2i + c = 0 ( note that i² = - 1 )
1 + 2i - 1 - 2 - 2i + c = 0 ← collect like terms on left
- 2 + c = 0 ( add 2 to both sides )
c = 2
Answer:
11.6
Step-by-step explanation:
<u>Solving with steps as below:</u>
- 31*r+1.1*(35−31)*r = 410.64
- 31r + 1.1*4r = 410.64
- 31r + 4.4r = 410.64
- 35.4r = 410.64
- r = 410.64/35.4
- r = 11.6
<u>Answer is:</u> r =11.6
I may have misunderstood the question but here you go.
Thirty-two minus fifteen.
Fifteen less than thirty-two.
Take fifteen from thirty-two
Subtract fifteen from thirty-two.
Answer:
306 square inches
Step-by-step explanation:
The surface are of a triangular prism is given as:
A = ab + 3bh
where a = Length of side
b = base length
h = height of the prism
If the dimensions are 3 times as great, that means a becomes 3a, b becomes 3b and h = 3h
Therefore, the new surface area becomes:
A1 = (3a * 3b) + 3(3b * 3h) = 9ab + 27bh
A1 = 9(ab + 3bh)
=> A1 = 9A
The surface area of the initial prism is 34 square inches, therefore, the surface area of the new prism will be:
A1 = 9 * 34 = 306 square inches
