Step-by-step explanation:
A.C
B.2w + 2(w + 3) = 72
2w + 2w + 6 = 72
4w + 6 = 72
4w = 72 - 6
4w = 66
w = 16.5
We can't use P = 2L + 2W because the sides have different lengths.
P = a + b + c + d
a = x
b = 2x
c = 2x - 2
d = x + 5
P = x + 2x + (2x - 2) + (x + 5)
P = <u>x + 2x + 2x</u> - 2 <u>+ x</u> + 5
P = 6x + 3
if x = 4:
P = 6 · 4 + 3
P = 24 + 3
P = 27
The teachings of buddha is the answer :-)
You have to solve the two equations by eliminating x or y
<span>2x+5y=10 </span>
<span>x-3y=1 </span>
<span>Multiply all terms of second equation by two and subtract from first equation, thus eliminating x </span>
<span>2x+5y-2x+6y=10-2 </span>
<span>11y=8 </span>
<span>y=8/11 </span>
<span>x=3y+1=3* 8/11+1=25/11 </span>
<span>11x+11y= 11*25/11+ 11*8/11 </span>
<span>= 25+8=33</span>
Answer:
Negative 4 and one-third divided by -3/4
Step-by-step explanation:
-4 1/3 / - 3/4
-4(3) +1 = -13/4
Divided by -3/4
-13/4 (-4/3) = 52/12
4 and 1/3
