Answer:
Step-by-step explanation:
<u>Given expression:</u>
<u>Multiply both sides by the conjugate of the denominator to get rid of the fraction:</u>
- (1 + i)(3 - 4i) / (3 + 4i)(3 - 4i) =
- (3 + 3i - 4i - 4i²) / (9 - 16i²) =
- (3 - i + 4) / (9 + 16) =
- (7 - i) / 25
if 1 inch is added, you would add 2 inches to to each side of rectangle.
You would have: W+2, and, L+2,
Now let W+2 = x and, L+2 = y
Total area = x*y=M
If 1 inch is added again, like above you add 2 inches to both sides, you would then have:
(x+2)(y+2)=M+52;
xy+2x+2y+4=M+52;
xy=M
2x+2y=48
x+y=48/2=24
Now solve :
W+2+ L+2=24
W+L=20
The perimeter is 2(W+L)=20*2 = 40 inches.
Jk=8x+6
J=(8x+6)/k
kL=6x+20
L=(6x+20)/k
JL=(8x+6)/k * (6x+20)/k
=(48x²+196x+120)/k²
You have to divide the 3 because 6&9 have 3 in common which will leave you with square root a^2 c^3.
