Answer:

12 inches.

Step-by-step explanation:

13^2 = h^2 + 5^2

h^2 = 169 - 25 = 144

Wht is -3(2x-1)+8=15
Svetllana [295]

Answer:

x=-\frac{2}{3}

Step-by-step explanation:

subtract -3(2x-1)+8=15

          -8    -8

2x-1=\frac{7}{3}

add both sides

2x-1+1=\frac{7}{3}+1

simplify again

2x-1+1=\frac{7}{3}+1=2x=-\frac{4}{3}

divide by 2

2x=-\frac{4}{3}

-2    -2

_________

2x÷2=1
