Answer:
5
Step-by-step explanation:
Put -2 where x is and do the arithmetic.
f(x) = 2x² -3
f(-2) = 2(-2)² -3 = 2(-2)(-2) -3 = 8 -3
f(-2) = 5
60x - 150 = 30
60x - 150 + 150 = 30 + 150
60x = 180
60x/60 = 180/60
x = 3
Answer:
?idk maybe it's supposed to be how long it's on the top but I know that not right sorry I dont get it
Answer:
2W=9
Step-by-step explanation:
You must first get the Length, which is 15, and multiply it by 2 and you get 30. You then subtract 30 from 48 and get 18. Since the equation has 2W, you have to divide 18 by 2, which gets you the answer 9.
Answer:
Area is Length x Width. So 16.47 = 6.1 x X. To find out was X is, we divide each side by 6.1, to find out that 2.7 = X
For the Perimeter (aka P) you need to add all of the sides. Since it is a rectangle the side that is given to us (6.1 length) we will double that value to 12.2, for the opposite side. In finding the Area we found that X is 2.7, which doubles to 5.2. Add these two values together equals 17.4, which is the Perimeter.
