Answer:A
Step-by-step explanation:
The difference of squares is 4m^2 - 20mn + 25n^2
Its a perfect square trinomial.
<h2>What is
perfect square trinomial?</h2>
A perfect square trinomial is the square of a binomial. It follows a pattern when it is factored, so that the first and last terms are perfect squares of monomials and the middle term is twice their product. If the pattern does not fit for a particular trinomial, it is not a perfect square trinomial.
<h3>How to solve this equation?</h3>
(-2m + 5n)^2
(-2m + 5n)(-2m + 5n)
4m^2-10mn-10mn+25n^2
4m^2 - 20mn + 25n^2
Thus, the difference of squares is 4m^2 - 20mn + 25n^2
Its a perfect square trinomial.

X would equal = 3 because -

+ 8 x 3 = 33.
9 + 24 = 33.
Hope this helps (:
Answer:
30
Step-by-step explanation:
We can ignore the fact they are similar altogether. It's known that all 3 angles of a triangle add up to 180, so:
180=102+48+m
180=150+m
30=m
Al's and Barbara's produce stands are illustrations of proportional relationships
- The unit rate at Al’s Produce Stand is 0.25, and the unit rate at Barbara’s Produce Stand is 0.24
- The equation at Al’s Produce Stand is y = 0.25x, and the equation at Barbara’s Produce Stand is y = 0.24x
<h3>Step 1: The constant of proportionality</h3>
From the question, we have the following ordered pairs
- Al’s Produce Stand: (x, y) = (6,1.50)
- Barbara’s Produce Stand: (x, y) = (13,3.12)
The unit rate is calculated as:

So, we have:
<u>Al</u>


<u>Barbara</u>


Hence, the unit rate at Al’s Produce Stand is 0.25, and the unit rate at Barbara’s Produce Stand is 0.24
<h3>Step 2: The equation</h3>
This is represented as

So, we have:
<u>Al</u>

<u>Barbara</u>

Hence, the equation at Al’s Produce Stand is y = 0.25x, and the equation at Barbara’s Produce Stand is y = 0.24x
<u>Step 3: The missing values</u>
This cannot be determined, as the table is not properly formatted
