Answer:
The side lengths are 10 by 7
Step-by-step explanation:
The area of a rectangle is
A = l*w
70 = (x - 11)(x - 8)
FOIL
70 = x^2 -8x-11x+88
Combine like terms
70 = x^2 -19x +88
Subtract 70 from each side
0 = x^2 -19x +88-70
0 = x^2 -19x+18
Factor
What number multiplies to 18 and adds to -19
-18*-1 =18
-18-1 = -19
0=(x-18)(x-1)
Using the zero product property
x-18=0 x-1=0
x=18 x=1
But x cannot x=1 because then the side lengths would be negative
x-18 = 10
x-11 = 7
The side lengths are 10 by 7
Lines on a railroad track are parallel lines.
Parallel lines are two or more lines that are in the same plane (flat space) and are always equal distances apart from each other at all points on the line.
Answer:
5250 g
Step-by-step explanation:
Given : Density of liquid is 1.50 g/ml
Volume of liquid is 3.50 liters
Solution :
Since 1 liter = 1000 ml
So, Volume of liquid is 3.50 liters = 3.5*1000 = 3500 ml.
Now 
Hence , the mass of the liquid is 5250 g.
