You add up all the sides, so for example, the first 1, 5+4+5+4=18
Answer:
Infinitely many solutions
Step-by-step explanation:
3x-3x-2=-2
3x-3x = 0
0-2= -2
-2 = -2 Which is true, meaning it can be infinitely many solutions
Answer:
150 m at 10 m/s
350 m at 50 m/s
Step-by-step explanation:
x + y = 500
x/10 + y/50 = 22
~~~~~~~~~~~~~~~~~
x + y = 500
5x + y = 1100
~~~~~~~~~~~~~~~~
x + y = 500
-5x - y = -1100
-4x = -600
x = 150
y = 350
80-64=24
24 is 30% of 80 so a decrease of 30%
Answer: Quadrilateral
Explanation:
Any four sided polygon is considered a quadrilateral since "quad" means "four". You can think of a quad bike, which has four wheels, to help remember this math term.
Usually in problems like this, we'll be given information about if certain sides are parallel or the same length. However, we don't this info, so we cannot narrow down this classification anymore.
