Answer:
Step-by-step explanation:
Width = w
Length = double the width = 2*w = 2w
Perimeter of rectangular tray = 60 in
2*(length + width) = 60
2*( 2w + w) = 60
2*3w = 60
6w = 60
Divide both sides by 6
w = 60/6
w = 10 in
length =2w = 2*10 = 20
length = 20 in
Width = 10 in
n - a number
14. Nine more than the square of a number: n² + 9.
15. Twice the difference between a number and ten: 2(n - 10)

Each meal takes up 2/3 pounds. To find the answer, divide how much Rita bought, 30, by how much is consumed each meal.
30/(2/3)=45
We saw under Functional Notation that y = 3x + 2 and f (x) = 3x + 2 can be interpreted as equivalent notations, where y has been replaced by f (x), or y = f (x). In y = 3x + 2, we see “y as a function of x”
False
I think that’s right because three times 5 is 15 increased by four is 19 not -8 so...
