Answer:
<h2>8 ft 11 in</h2>
Step-by-step explanation:
It's a matter of proportions.
Let's call them A and B. Now, let's make an equation.

Now that we know that...

Answer:
x=0.5×1±√33
Step-by-step explanation:
x+8=x² and 2(x+8)=2x²
x²-x-8=0
P = 3r + 2s --> P - 3r = 3r - 3r + 2s
2s = P - 3r --> 2s/2 = (P - 3r)/2
s = (P - 3r)/2
Answer:
x = 1/9
Step-by-step explanation:
3^ (x+1) = 9 ^ (5x)
Replace 9 with 3^2
3^ (x+1) = 3^2 ^ (5x)
We know that a^b^c = a ^(b*c)
3^ (x+1) = 3^(2 * (5x))
3^ (x+1) = 3^(10x)
The bases are the same so the exponents are the same
x+1 = 10x
Subtract x from each side
x+1-x = 10x-x
1 = 9x
Divide each side by 9
1/9 = 9x/9
1/9 =x
