Answer:
2x²y⁴
Step-by-step explanation:
Area = W × L
W = A / L = 
= 2x²y⁴
Answer:
The answer you chose is correct
Step-by-step explanation:
The midpoint between these two would be -7, as you would add these two numbers, and then divide by two.
(a) 95 = (x+7)*(x-7)
(b) 95 = (x+7)*(x-7)
Expand the brackets:
95 = x² -7x + 7x -49 = x² - 49
Subtract x² from both sides:
95-x² = -49
Subtract 95 from both sides:
-x²=-49-95
-x²= -144
Divide both sides by -1 to get rid of the negative numbers:
-x²/-1=-144/-1
x²=144
Take the square root of 144:
x = ± squareroot of 144
x = 12 or -12
x = 12 because you cannot have a negative age so Trina is 12 years old.
30/8=3.75
So, you need 4 trays, since you can't have 75% of a tray.
Hope this helps
