Sounds like the common legnths that work
aka pythagorean tripples so
3,4,5 is one of them
therefor we know that
6,8,10 is another since we just multiplied them all by 2
there are some that aren't multiplules like
5,12,13
these are just some
Answer:
x = 45
Step-by-step explanation:
(2x + 6)/3 = (5x - 1)/7
<em>Cross multiply</em>
7(2x + 6) = 3(5x - 1)
<em>Expand both expressions</em>
14x + 42 = 15x - 3
<em>Collect like terms</em>
42 + 3 = 15x - 14x
45 = x
x= 45
<em>Check:</em>
7(2*45 + 6) = 3(5*45 - 1)
7(90 + 6) = 3(225 - 1)
7 * 96 = 3 * 224
672 = 672
Answer:
$672
Step-by-step explanation:
First find the area so:
5*4=20ft
2^2*3.14=12.56ft
20+12.56=32.56ft
Second find the price for the area:
32.56*12=$672
Hopefully it's correct!
