Answer:
13cm
Step-by-step explanation:
P=2l+2w
56=2(15)+2w
56=30+2w
26=2w
w=13
Answer:
The answer is 1600.
Step-by-step explanation:
Just multiply 400 by 4.
Answer:
x = 5.5
EF = 14
Step-by-step explanation:
We can use ratios to solve
AG 7
----------- = -----------------
EG 2x+3
We know that EG is 2 times AG since A is the midpoint
AG 7
----------- = -----------------
2 AG 2x+3
Canceling like terms
1 7
----------- = -----------------
2 2x+3
Using cross products
1 (2x+3) = 2*7
2x+3 = 14
Subtract 3 from each side
2x+3-3 = 14-3
2x =11
Divide by 2
x = 11/2
x = 5.5
EF = 2x+3 = 2*5.5+3 = 14
Answer:
Step-by-step explanation:
if 506 is 110 percent
than 100 percent would be 460
First you would have to do 8 x 3, which is 24 because an octagon has 8 sides and it says with three times as large. Then you would do 24 x 50 cm2 which is 1,200 centimeters. And so the area would be 1,200 cenimeters. I don't know. But I am REALLY, REALLY, REALLY, REALLY, REALLY, REALLY, REALLY , REALLY, REALLY, REALLY, REALLY, REALLY, REALLY, REALLY, REALLY, REALLY, positive about my answer. Hope this helps! If anyone else answers it and the answer is different than mine, you can pick mine or theirs. :)
