Answer:
m=10
Step-by-step explanation:
hypotenuse is 15+5=20
to find shorter leg <em>m</em> divide the hypotenuse by 2
20÷2=10
A= 42in²
P = 2l + 2w so
(21 x 2) + (2 x 2)
42 + 4 = 46
46 = 21 by 2
Now let's do 6 and 7
(6 x 2) + (7 x 2)
12 + 14 = 26
46 > 26
so 21 by 2 has greater P (perimeter)
Answer:

Let x be the price of one pie.
3x + 1 = x + 9
3x + 1 - 1 = x + 9 - 1
3x - x = x - x + 8
2/2x = 8/2
x = 4
The pies cost $4
