David purchased some cookies at the cost of
5 for $4 (5/4=1.25) and
sold them at 4 for $5(4/5=0.80).
To find cost per cookie subtract 1.25-0.80=0.45
David made a profit of $180 in total ( divide profit per cookie cost: 180/0.45= 400)
How many cookies did David purchase to make that much money?
He needed to make 400 cookie to make the profit of $180.
In parallelogram the opposite sides are equal. Therefore we have the equation:

In the parallelogram, the sum of measures of the angles at one side is 180°. Therefore we have the equation:

Answer:
c = a + b → c = 7 + 7 = 14
A. 14
To simplify the equation, we have y = 
<h3>How to simply the expression</h3>
Given the expression
y-8 = 3/4x [x-(-6)]
First, expand the bracket
= 
Make 'y' the subject of formula
y = 
Thus, to simplify the equation, we have y =

The HA Theorem is a special case of proving that two triangles are congruent.
It states that if both hypotenuses and a pair of acute angles of two right triangles are congruent, then the triangles are congruent.
