X/5 + x/2 =14
⇒ 2x/10 + 5x/10 = 14 (common denominator)
⇒ 7x /10 = 14
⇒ 7x* (10/10) = 14*10
⇒ 7x = 140
⇒ (7/7)*x= 140/7
⇒ x= 20
The final answer is x=20.
Hope this helps~
First one: A=5
Second one: no solution
<h3>
Answer: x = (
y-2)^2 +
5</h3>
In other words, y-2 goes in the first box and 5 goes in the second box.
=================================================
Work Shown:
y^2 - 4y - x + 9 = 0
y^2 - 4y + 9 = x
x = y^2 - 4y + 9
x = y^2 - 4y + 4 + 5 .... rewrite 9 as 4+5
x = (y^2-4y+4) + 5
x = (y-2)^2 + 5 .... apply the perfect square factoring rule
So we'll have y-2 go in the first box and 5 goes in the second box
note: One version of the perfect square factoring rule says (a-b)^2 = a^2-2ab+b^2.
