Answer:
3, 5, 7
Step-by-step explanation:
1st number: (2k+1)
2nd number: (2k+3)
3rd number: (2k+5), k∈Z
3*[(2k+1) + (2k+3)] = 3 + 3*(2k+5)
3*(4k+4)=3+6k+15
12k+12=18+6k
6k=6
k=1
1st number: (2k+1) = 3
2nd number: (2k+3)=5
3rd number: (2k+5)=7
ANSWER: -60
EXPLANATION: To solve for (-10) - |(-20) – (+30) |, we need to do:
−10−| −20 − 30|, which equals −10−|−50|. Next, we do −10−50, which is -60.
−10−|−20−30|
= −10−|−50|
= −10−50
= −60
The following is ?
There’s no following
Bx + Cy = D
Solve for y . . .
*subtract Bx from both sides
Bx - Bx + Cy = D - Bx
Cy = D - Bx
*now divide both sides by C
Cy/C = (D - Bx)/C
Cy/C = D/C - Bx/C
y = D/C - (B/C)x
<u><em>y = -(B/C)x + D/C</em></u>
Rewrite the given number as

If it's purely real, then the complex part should be 0, so that

as required.
