Answer:

Notice the line in between the 61 degrees and b

Step-by-step explanation:

I can't remember what this kind of angle is called, but when you have a straight line with another line coming out of it like this, then the sum of both angles has to equal 180 so what would you add to 61 to get to 180?

divide each side by 3 to get:

t = -39 2/3

Write the expression as a square of a monomial.

frozen [14]

Answer:

The square of a monomial is $(9x^2)^2$

Step-by-step explanation:

Consider the provided monomial.

$81x^4$

We need to Write the expression as a square of a monomial.

The above expression can be written as:

$9\times 9\times x^2\times x^2$

$9^2(x^2)^2$

$(9x^2)^2$

Hence, the square of a monomial is $(9x^2)^2$
