The formula for perimeter of a rectangular field is P = 2L + 2W. Find the length of the field if the perimeter is 24m and the width is 5m.

The length is 7 meters

Step-by-step explanation:

Formula: P = 2L + 2W

Plug in 24 for the perimeter and 5 for the width

New equation: 24 = 2L + 2(5)

Simplify: 24 = 2L + 10

Subtract 10 from both sides: 24 - 10 = 2L + 10 - 10

Simplify: 14 = 2L

Divide both sides by 2: L = 7

L = 7

d. and h.

Step-by-step explanation:

from what I can see from the unfocused picture, there are the following whole number points in the function :

(1, 3)

(2, 2)

(5, 1)

a. and d. are the only ones supporting (1, 3). x = 1 makes the square root 0 and therefore y (the functional result) 3.

but (2, 2) or (5, 1) then show we need the negative square root. x = 2 makes the square root 1, and we need -1 to be added to 3 to create 2 as y value.

so, d. is correct.

the square root makes it necessary that x >=1, because for smaller x values the square root would be for a negative value, which is not defined for real numbers.

and the maximum for y is for x=1 : y=3.

for larger x values the y values just go further down.

so, h. is the second right answer.
