The answer is c 16. Square cm
Answer:
15
Step-by-step explanation:
take 9 and divide by -3 and you get -3
then 21 divided by -7 is -3
so, you do -5 multiplied by -3 and get 15.
you can then take 15 and divide it by -3 and get 5
Answer:
It's linear, so its proportional/has a relationship.
The y/x thing means slope, so take the slope -- which is 9.
Answer:
k = -2
Step-by-step explanation:
Divide 22 by -11 as well as -11k by -11
(You have to divide both sides by the number that k is to find your answer)
22 divided by -11 = -2
-11k divided by -11 = k
meaning you would get the answer of k = -2
Answer:
- 1 - 23i
Step-by-step explanation:
The expression is
(3+i)-(5-7i)(-2+2i)
The answer to your question can be found in the image attached below.
We need to multiply the terms and add them together
(3+i) - [ (5)(-2+2i) +(-7i)(-2+2i) ]
= (3+i) - [ -10 +10i + 14i -14i^2]
= (3+i) - [ -10 +10i + 14i +(14)]
= (3+i) - [ 4 + 24i ]
= (3+i) - 4 - 24i
= - 1 - 23i
