Step-by-step explanation:

Follow PEMDAS Order Of Operations

(2 + 4): 6

\bold{2\cdot \:6^0+3\left(18+6\right)^0}

(18 + 6): 24

\bold{2\cdot \:6^0+3\cdot \:24^0}

\bold{6^0: \ 1}

\bold{2\cdot \:1+3\cdot \:24^0}

\bold{24^0: \ 1}

\bold{2\cdot \:1+3\cdot \:1}

\bold{2\cdot \:1: \ 2}

\bold{2+3\cdot \:1}

\bold{3\cdot \:1: \ 3}

\bold{2+3}

Plz help me .. I am really stumped!!!!!!! part of the set for a play is a big triangular piece of plywood. the area of the trian
saul85 [17]
The way to find the area of a triangle is A=\frac{B*H}{2}
if the base is 3 feet longer then the height we can write it like this B=H+3

now we can add it to our area equation
20=\frac{H(H+3)}{2}
20=\frac{ h^{2} +3h}{2}
40=H^{2}+3H
10\frac{1}{3}=H^{2}
h=3.2ft

I need help!!

Answer:

The exact solution is

x = \frac{Ln(60)}{7*Ln(5)}

And the approximation to three decimal places is:

x = 0.363

Step-by-step explanation:

Here we have the equation:

5^{7*x} = 60\\

Now we can remember a property of the natural logarithm function:

Ln(a^n) = n*Ln(a)

Now we can apply the Ln( ) function to both sides of that equation to get:

Ln(5^{7*x}) = Ln(60)

Then we get:

7*x*Ln(5) = Ln(60)

Solving that for x we get:

x = \frac{Ln(60)}{7*Ln(5)}  = 0.363

So the exact solution is:

x = \frac{Ln(60)}{7*Ln(5)}

And the approximation to three decimal places is:

x = 0.363
