If (x - 2) is a factor of 2x³ + x² - 3 then for the value of x = 2 the polynominal is equal zero.
Substitute:
2 · 2³ + 2² - 3 = 2 · 8 + 4 - 3 = 16 + 4 - 3 = 17 ≠ 0
Answer: B) (x - 2) is not a factor.
First, find the area for the kitchen floor: 16.5*15=247.5 squared feet
Then find the area for one tile: 0.5*0.5=0.25 squared feet
Finally, divide the mayor area between the minor: 247.5/0.25= 990 tiles.
Also you can do it in this another way:
First, divide length of the kitchen floor between the length of one tile: 16.5/0.5=33
Then, do the same for the height: 15/0.5=30
Finally multyply both results: 33*30= 990 tiles.
Answer:
1)Evaluate the left-hand side expression at the given value to get a number.
2)Evaluate the right-hand side expression at the given value to get a number.
3)See if the numbers match.
Sorry if wrong
Answer:
1/5 is the fraction of 20%.
5x-22=-7
Move -22 to the other side
Sign changes from-22 to +22
5x-22+22=-7+22
5x=-7+22
5x= 15
Divide both sides by 5 to get x by itself
5x/5= 15/5
x= 3
answer:
x= 3
