A rectangle has an area of 28 ft2. If the width of the rectangle is 5 ft, what is the length?

1 answer:

5 0

Area of a Rectangle = Length x Width
28 ft² = L x 5ft
28 ft² / 5ft = Length
5.6 ft = length. CHOICE A.

Perimeter of a Rectangle = 2(L + W)
20 ft = 2(L + 4)
20 ft = 2L + 8
20 - 8 = 2L
12 = 2L
12/2 = 2L/2
6 ft= Length CHOICE A.

Answer:

81 m

Step-by-step explanation:

Since x is seconds after takeoff, the value of x at takeoff is 0. You are being asked to find H(0).

H(0) = -3(0 -3)^2 +108 = -3(9) +108 = 81

The height of the hovercraft at the time of takeoff is 81 meters.

USPshnik [31]

Answer: A, because it is a 30, 60, 90 triangle. To get the 34 they had to times the number by 2 so you divide that by 2 and it gives you 17 then you have the square root of 3* 17, that doesn’t mathematically work so it stays as 17*the square root of 3
