Hello,
A fraction is not defined if its denominator is null.
3x²-75=0
==>3(x²-25)=0
==>(x+5)(x-5)=0
==>x=-5 or x=5
Answer:
C 5 km
Step-by-step explanation:
so, 5 cm on the map correlates to
5×100000 = 500000 cm in reality.
100 cm = 1 m
1000 m = 1 km
so, 500000 / 100 = 5000 m.
5000 / 1000 = 5 km
Answer:
0.422 L
Step-by-step explanation:
A little-used fact is that a <em>liter</em> is a <em>cubic decimeter</em>. The dimensions of your cube are ...
edge length = 75 mm = 75/1000 m
Since a decimeter is 1/10 of a meter, we want the denominator to be 10. Moving the numerator and denominator decimal points 2 places to the left, we get ...
edge length = 0.75/10 m = 0.75 dm
Then the volume of the cube is ...
V = (0.75 dm)^3 = 0.422 dm^3 = 0.422 L
Answer:
Step 1
Use the distributive property to multiply 22 by x-5x−5.
|2x-10|+11=17∣2x−10∣+11=17
Hint
Expand using distributive property.
Step 2
Subtract 1111 from both sides.
|2x-10|=17-11∣2x−10∣=17−11
Step 3
Subtract 1111 from 1717 to get 66.
|2x-10|=6∣2x−10∣=6
Hint
Subtract one term from another.
Step 4
Use the definition of absolute value.
2x-10=62x−10=6 2x-10=-62x−10=−6
Step 5
Add 1010 to both sides of the equation.
2x=162x=16 2x=42x=4
Step 6
Divide both sides by 22.
x=8x=8 x=2x=2
Solution
x=2x=2
x=8x=8
