2/X^2=4/X+1 times by both denominators
2(x+1)=4(x^2)
2x+2=4x^2
4x^2-2x-2=0
(2x+1)(2x-2)=0
x=2x+1 or 2x-2
x=-1/2 or 1
If x is the number of chairs in a row
4x + 5 = 2x + 17
2x = 12
x=6
There are 6 chairs in each row. Now you have to find the total
4x+5 = 4(6)+5 = 29
And now double check
2(x) + 17 = 2(6)+17 = 29
Liam has 29 Chairs
The HL (hypotenuse leg) theorem states that any two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles.
Step-by-step explanation:
AE is congruent to itself.
AB is congruent to DE
<ADE and <EBA are right angles, making them right triangles
Therefore ADE is congruent to EBA by the HL theorem.
