To find the value of x, compare the equal sides, As two angles are equal so the sides opposite to these angles are also equal.
Compare the sides.
9x-8=28
Add 8 to both sides
9x=36
Divide both sides by 9.
x=4

Answer:
The coefficient of y² will be 1, which we can see when we expand the expression:
(x + y)²
= (x +y)(x + y)
= x² + xy + xy + y²
= x² + 2xy + y²

Step-by-step explanation:
Monday
1.) <em>1250 gallons of water for 1 ounce of Granular chlorine.</em>
<em></em>
2.) <em>w = 1250c</em>
Tuesday
9.5% of 50
0.095 × 50 = 4.75
<em>The fee costs $4.75</em>
Since the fee will be deducted from the selling price..
50 - 4.75 = 45.25
<em>Once he pays for the fee, he'll make $45.25.</em>

Wednesday
To get 1 cup of sugar, you multiply 4 to 1/4 meaning to find the proportional amount of flour used, you have to multiply 2/3 by 4
2/3 × 4 = 8/3
<em>She should use 2 ²/₃ cups of flour</em>
Since in the new recipe, we're multiplying everything by 4..
16 × 4 = 64
With this new recipe, she can make 64 cookies.
Thursday
4800 ÷ 6400 = 0.75
0.75 × 100 = 75
4800 is 75% of 6400
100 - 75 = 25
<em>So, the cost of health insurance for the family increased by 25%</em>
