Answer:

276m²

Step-by-step explanation:

area of path = area of outer rectangle - area of inner rectangle

dimensions given of inner = l-40m

b - 25m

thickness = 2m

new l = 40+2+2 = 44m = L

new b = 25 + 2+ 2= 29m = B

hence,  LB- lb = area of path

= 44*29 - 40*25

= 1276 - 1000

= 276m²

Answer:

276m^2

Step-by-step explanation:

area = 2(25*2) + 2(40*2) + 4(2*2)

area = 2(50) + 2(80) + 4(4)

area = 100 + 160 + 16

area = 276m^2

Speed = distance / time
speed = 1(mile) / 4 (minutes)
speed = 0.25 miles per minute
s = 0.25m <== ur equation

there are 60 minutes in an hr....so sub in 60 for m
s = 0.25(60)

Which is the following points is NOT a solution to the inequality y &gt; - x + 3? —a. ( -2,6)b. (5,-1)c. (2,0)d. (0,3)
CaHeK987 [17]

Given -

y > - x + 3

To Find -

The points which is NOT a solution to the inequality

Step-by-Step Explanation -

We will put the value of each in inequality and then see if it satisfies the given condition or not.

a. ( -2,6)

So, x = -2 and y = 6 in y > - x + 3

= 6 > - (-2) + 3

= 6 > 5 (Correct Solution)

b. (5,-1)

So, x = 5 and y = -1 in y > - x + 3

= -1 > -5 + 3

= -1 > -2 (Correct Solution)

c. (2,0)

So, x = 2 and y = 0 in y > - x + 3

= 0 > -2 + 3

= 0 > 1 (Incorrect Solution)

d. (0,3)

So, x = 0 and y = 3 in y > - x + 3

= 3 > -0 + 3

= 3 > 3 (Incorrect Solution)

Final Answer -

The points which is NOT a solution to the inequality =

c. (2,0)

d. (0,3)
