Consider the numbers z= 2 + 5i, w = -3- 2i, and u=-1+2i.
z+w is equal to -1+vi
w-u is equal to - 4i
u + w is equal to -4 -
Answers
Answer:
3, 2, 0
Step-by-step explanation:
trust me
The resultant value of vectors are:
1. z + w = -1 + 3i.
2. w - u= -4 - 4i
3. u + w = -4.
Given:
z = 2 + 5i
w = -3 - 2i
u = -1 + 2i
1. z + w:
Adding the real and imaginary parts separately gives
(2 + 5i) + (-3 - 2i) = (2 - 3) + (5 - 2)i
= -1 + 3i
Therefore, z + w is equal to -1 + 3i.
2. w - u:
Subtracting the real and imaginary parts separately gives
(-3 - 2i) - (-1 + 2i) = (-3 + 1) + (-2 - 2)i
= -4 - 4i
Therefore, w - u is equal to -4 - 4i.
3. u + w:
Adding the real and imaginary parts separately gives
(-1 + 2i) + (-3 - 2i) = (-1 - 3) + (2 - 2)i
= -4
Therefore, u + w is equal to -4.

(I will mark brainliest) Use this equation to solve for the missing variable:
y = 8x + 12
If x = -6, y = _____
If y = 13, x = _____
Answers
Answer: x would be 1/8 and y would be -36
Step-by-step explanation:
To find put y you would plug in -6 for x. So it would be y=8(-6)+12. Then you multiply the 8 and -6 to get -48, y=-48+12. Then subtract 48 from 12 and that is -36 so y=-36. To solve for x you would plug in the y or 13 into the equation. So, 13=8x+12. Then you would have to solve. 12 minus 13 is 1 and the you are left with 1=8x then you divide 1/8 and 8x/8 and you get x=1/8. Hope this helped!

Andre is planting saplings (baby trees). It takes him 30 minutes to plant 3 saplings. If each sapling takes the same amount of time to plant, how long will it take Andre to plant 14 saplings? If you get stuck, consider using the table.
Answers
Answer:
140 minutes
Step-by-step explanation:
If it takes him 30 mins to plant three, then 30 divided into three equal groups is 10. Then we multiply 14 and 10 together since it takes Andre ten minutes to plant each sapling. This means that the 14 saplings takes ten minutes EACH to plant.
