Answer:
I'm not sure if you meant to capitalize the first "x". If you did, then the correct answer is:
Xx+4X+5x+20
If you didn't, the answer is:
x^2+5x+20
Work:
1) X*x=Xx
2) X*4=4X
3) 5*x=5x
4) 5*4=20
Answer: pi/4 and -1
Step-by-step explanation:
Exterior angle sum of an polygon (shape) is 360 degrees (this is a property)
x + 98 + 41 + 76 + 86 = 360
Therefore x = 59
Please double check the equation I have written. Your picture is a bit blurry therefore I can really tell what number is 6 and 8. Sorry
Plenty of samples around!
ft per sec e. g., 88 ft / sec = 60 mph
miles per hour e. g., 55 mph
4 quarts = 1 gallon
All can be written in other ways, such as
1 gall
-------- This is a quarts - to - gallon conversion factor
4 qts
