The area of a rectangular flower bed is 24 square feet. The perimeter of the same flower bed is 22 feet. What are the dimensions
Ray Of Light [21]

ANSWER

B. 3 ft by 8 ft

EXPLANATION

The area is given as 24 square feet.

This implies that,

l \times w = 24

The perimeter of the rectangular field is given as 22 feet.

This implies that,

2(l + w) = 22

Or

l + w = 11

We make w the subject in this last equation and put it inside the first equation.

w = 11 - l

When we substitute into the first equation we get;

l(11 - l) = 24

11l -  {l}^{2}  = 24

This implies that,

{l}^{2}  - 11l + 24 = 0

(l - 3)(l - 8) = 24

l = 3 \: or \: 8

When l=3, w=24

Therefore the dimension is 3 ft by 8 ft

Write the equation in slope intercept form. what are the slope and y-intercept?
Leno4ka [110]
Slope intercept is basically solve for y
y=mx+b
m=slope
b=yintercept

-3x-10y=7
add 3x to both sides
-10y=3x+7
divide both sides by -10
y=-3/10x-7/10

slope is -3/10
yintercept is -7/10 or at point (0,-7/10)

Let point L be between M and N on MN. Given that MN=31, ML= h-15 and LN = 2h-8. Find LN.
shtirl [24]
Given that <span>point L is between M and N on MN. Then
MN = ML + LN
31 = h - 15 + 2h - 8 = 3h - 23
3h = 31 + 23 = 54
h = 54/3 = 18

Therefore, LN = 2(18) - 8 = 36 - 8 = 28.

kherson [118]

Answer:

Step-by-step explanation:

32.12 meters below sea level. The diver ascended to the surface at a rate of 8.8 m/min. So the diver ascended 3.65 meters a minute.

a) Use d=rt. D=distance, t= minutes, r=rate

d=8.8t

b) The distance will never be a negative number because you can't have a negative distance to something.

c) 3.65 minutes for the diver to reach the surface.
