Answer:

length is 6feet and width is 3 feet

Step-by-step explanation:

Area of the garden = LW

Perimeter of the garden = 2(L+W)

L is the length

W is the width

Given

Area = 18 square feet

Perimeter = 18feet

Substitute

18 = LW ... 1

18 = 2(L+W)

9 = L+W .... 2

From 2;

L = 9-W

Substitute into 1

18 = (9-W)W

18 = 9W-W²

W²-9W+18 = 0

W²-6W-3W+18 = 0

W(W-6)-3(W-6) = 0

W-3 = 0

W = 3 feet

Since L = 9-W

L = 9-3

L = 6feet

Hence the length is 6feet and width is 3 feet

Mai biked 7 and 1/4 miles today, and Noah biked 3 5/8 miles. How many times the length of Noah's bike ride was Mai's bike ride?
Firdavs [7]

Answer:

2 times

Step-by-step explanation:

Mai biked 7\frac{1}{4} = \frac{29}{4} miles today and Noah biked 3\frac{5}{8} = \frac{29}{8} miles  today.

We are asked how many times the length of Noah's bike ride was Mai's bike ride.

Therefore, the length of Mai's bike ride was (\frac{29}{4} \div \frac{29}{8})  = 2 times the length of Noah's bike ride.  

Therefore, we will take option B will be correct. ( Answer )

2. Find the<br> slope of the<br> line between<br> (8, 6) and<br> (20, -14)
Natalka [10]

Answer:

slopee = 5/3

Step-by-step explanation:

The  slope of a line is defined by the rise (the change in y-value) divided by the run (the change in x-value).  Here, the change in y-value is 6 - (-14) = 6 + 14 = 20.  The change in x-value is 20 - 8 = 12.  Therefore, the slope is 20/12 or (simplified) 5/3.

6(x-2)=5x+3x+8 solve for x.
Mnenie [13.5K]

Answer:

x = -10

Step-by-step explanation:

 6 • (x - 2) -  (8x + 8)  = 0

Pulling out like terms :

3.1     Pull out like factors :

  -2x - 20  =   -2 • (x + 10)

Equation at the end of step  3  :

 -2 • (x + 10)  = 0

Equations which are never true :

4.1      Solve :    -2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2      Solve  :    x+10 = 0

Subtract  10  from both sides of the equation :

                     x = -10

One solution was found :

                  x = -10
