Answer:
x²+ x = 0
x ( x +1 ) = 0
x = -1
x³-25x=0
x ( x² - 25 ) = 0
x² = 25
x = 5
x²=4x
x² - 4x = 0
x ( x- 4 ) = 0
x = 4
4x²-4x=1
4x²-4x - 1 = 0
4 x² - 2x - 2x - 1 = 0
2x ( 2x - 1 ) - 1 ( 2x- 1 ) = 0
2x- 1 ) ² = 0
2x = 1
x = 1/ 2

Answer:
Triangle HIK is congruent to triangle JGK
KI = KG (CPCT)
HK = JK (CPCT)
Angle HKG = angle JKI
Therefore triangle HKG is congruent to triangle JKI
GH = IJ (CPCT)

Answer:
20,250
Step-by-step explanation:
To find certain percentage of a number, we first convert the percentage into decimal and then multiply that decimal with the number.
<u>Converting Percentage to Decimal Rule:</u>
- Divide the percentage by 100
So, 30% would become:
30/100 = 0.3
Now, we multiply:
0.3 * 67,500 = 20,250
<span>3200/(1/3)=
3200*3/1
=9600 m
=9.6km
Final answer: 9.6 km
