Hi! I believe it’s D but not 100% sure- HOPE IT HELPS
So, 5 x (-3) + 7 = -15 + 7 = - 8 , but not 4;
Then, -3 is not a solution to 5x + 7 = 4;
Answer:

Step-by-step explanation:
We know i×i=i^2 which has value of -1.
We will multiply numerator and denominator by i so the denominator will no longer contain imaginary part(s).
Also multiplying by i/i does not change the value of the fraction because i/i=1.
Numerator × i gives (-5+i)i=-5i+i^2=-5i-1
=-1-5i.
Denominator × i gives (2i)i=2i^2=-2.
So the simplified version of this fraction given is:

The last simplification come from me multiplying fraction by -1/-1.
Answer:
3. w=P/2-L
Step-by-step explanation:
<u>Given formula:</u>
<u>Solving for w:</u>
- P=2(l + w)
- P/2 = 2(l + w)/2
- P/2 = l + w
- P/2 - l = l + w - l
- P/2 - l = w
- w = P/2 - l
<u>Correct answer choice is:</u>
