3p-8=13-4p
+4 +4
so now you got 7p-8=13
+8 +8
and now you have 7p=21 and how many times does 7 go in to 21 and you should get p=3 and there you go
the measure is 140, I basically summed all of the angles of a polygon of “n”, which is 7, then I did 7-2 times 180 (900) so I can finally add up all of your measurements
Answer:
50 feet
Step-by-step explanation:
We have to find the perimeter of the fence surrounding the garden.
2l+2w
2(15) + 2(10)
30 + 20
= 50
50 feet will be needed.
Answer: 18
Step-by-step explanation:
The circumference formula is C= 2r
r being the radius, so you can just plug in.
C= 2(9) = 18
You would write the expression as nP +nL=cost because it’s the number of plagues that he buys plus the number of loaches that he buys
