This is a perfect square trnomial
(a+b)²=a²+2ab+b²
we see that a=5x and b=2
(5x)²+2(5x)(2)+2²=0
factor
(5x+2)²=0
set equal to zero
5x+2=0
5x=-2
x=-2/5
Step-by-step explanation:
= -4 + 12 + (-9)
= -4 + 12 - 9
= -4 + 3
= -1
Area= length * height
21*9 = 189cm^2
1/8 or 1/6
which is greater
1) Lets make the fraction into a percent
1/8 ⇒ 1 ÷ 8 = 0.125
0.125 x 100 = 12.5%
1/6 ⇒ 1 ÷ 6 = 0.16....
0.16.. x 100 = 16.6.. = 16.7%
1/8 is bigger since it is closer to 0.
Hope this helps
