Answer:
Molly
Step-by-step explanation:
Brady did not properly create a square.
The square of a binomial is ...
(a -b)² = a² -2ab +b²
Where a²=x² and -2ab = -4x, you find b=2. The constant term in the square is 2²=4. Brady shows it as -4, which is incorrect.
Molly's work is correct.
Since A number line going from 1 to 2 with 5 equal spaces between 1 and 2the number represented by point B is 1⁴/₅
The question has to deal with proportion
<h3>What is proportion?</h3>
Proportion is the measure of a variable or quantity relative to another.
<h3>How to calculate which number represents point B?</h3>
Since A number line going from 1 to 2 with 5 equal spaces between 1 and 2, the measure of a sub-unit between 1 and 2 is
= 1/5
So, each sub-unit measure 1/5
Since point B is one mark to the left of 2, we have that point B is y = 2 - 1/5 = (10 - 1)/5
= 9/5
= 1⁴/₅
So, the number represented by point B is 1⁴/₅

An expression is just taking something in word form and writing it down in mathematical form.
Answer:
the answer is four
Step-by-step explanation:
Because first you do 36/4 which gets you to 9 and then subtract it by 5 to get 4!
