Step2247 [10]

Answer:

$c = 41$

Step-by-step explanation:

${c}^{2} = \sqrt{ {a}^{2} + {b}^{2} }$

$c = \sqrt{ {a}^{2} + {b}^{2} }$

$c = \sqrt{ {9}^{2} + {40}^{2} }$

$c = \sqrt{81 + 1600}$

$c = \sqrt{1681}$

$c = 41$

THIS IS FOR MY TEST PLEASE HELP

AVprozaik [17]

2(3x+4y) = 2(24)
6x+8y = 48
Add both the equations
6x + 8y = 48
+ x - 8y = -20
—————————
7x = 28
x = 28/7
x = 4

Plug in this value in the second equation

(4) - 8y = -20
-8y = -24
y = -24/-8
y = 3

Therefore:
x = 4
y = 3
