A right triangle has one leg that is 24 feet long and another that is 6 feet long what is the perimeter? A right triangle had a

natka813 [3]

In the first example we must calculate hypotenuse's length using pythagorean theorem
c^2 = a^2 + b^2 => c^2 = 24^2 + 6^2 = 576 + 36 = 612 =>
c = square root of 612 + 24.74 ft
perimeter P1 = a+b+c = 24+6+24.74= 54.74 ft
In the second example we must calculate second leg in the same manner
a^2 = c^2 - b^2 => a^2 = 15^2 - 9^2 = 225 - 81 = 144 =>
a = square root of 144 = 12
perimeter P2= 15+9+12=36 ft
Good luck !!!!

2x + 3 = 9x – 5<br> Need help please

BartSMP [9]

Answer: 1 $\frac{1}{7}$

Please read the whole thing and make sure you understand. Trust me, only copying and not learning will only make math harder.

Step-by-step explanation:

2x + 3 = 9x - 5

Add 5 to both sides, cancelling off the 5 on the right

2x + 3 + 5 = 9x

2x + 8 = 9x

Subtract 2x from both sides, cancelling off the 2x on the left

8 = 9x - 2x

8 = 7x

Divide each side by 7, cancelling of the 7 from the x on the right

8 / 7 = x

1.4285714286... = 7

1 $\frac{1}{7}$
