Line one is perpendicular
Second line is is neither.
Answer: 18 rows.
Step-by-step explanation:
The theatre has 4 chairs in a row.
There are 5 rows.
If we consider rows as unit, then we observed that
Length = 4 rows
Width = 5 rows
Perimeter of Rectangle = 2(length +breadth)
= 2(5+4)
= 2(9)
=18 rows
Hence, the perimeter is 18 rows.
1/2x + 3 = 2/3x + 1....multiply everything by the common denominator of 6
3x + 18 = 4x + 6
3x - 4x = 6 - 18
-x = - 12
x = 12 <====
multiplying by the common denominator will get rid of the fractions
I think it’s (6,4) because it’s the highest point of the graph.
Answer: 30
Step-by-step explanation:
you should draw a model of this. Draw a rectangle labeling opposite sides as x (width). then label the other 2 sides as x-6 (which is the length). If x(x-6)=720, then you should be able to solve. x^2 (squared)-6x=720. Then make it into a quadratic. x^2-6x-720, and solve. You'll get (x-30) and (x+24) meaning x can either equal 30, or -24. If you didn't know- you get positive 30 because x-30=0 (that's what (x-30) and (x+24) means). Obviously a side length can't be negative, so it's 30
