It will be C because 6×2 +6×2 = 24 and 12×2 is 24.
<u> P = 2 (L + B)</u>
Divide each side by 2 : P/2 = L + B
Subtract B from each side: <em>P/2 - B = L</em>
26)
the sum of all internal angles=(sides-2)*180
720=(x/25-2)*180
4=x/25-2
6=x/25
150=x degrees per angle of A
use angle of A to calculate amount of sides of A:
150=(n-2)*180/n
150=180-360/n
360/n=30
12=n=sides of A
-> F
27)
Donald=500-6*t
Wendy=400-4*t
W=D
500-6t=400-4t
100-6t=-4t
100=2t
50=t
-> A
Let me know if you need me to explain!
1. Isolate the y. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
First, multiply 12 to both sides
-y/12(12) = 6(12)
-y = 6(12)
-y = 72
Isolate the y. Divide -1 from both sides
-y/-1 = 72/-1
y = -72
-72 is your answer for y

2. Isolate the x. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
x/4 = 8
First, multiply 4 to both sides
x/4(4) = 8(4)
x = 8(4)
x = 32
32 is your answer for x
