5(4x+6)=6x+9. Help...

1 answer:

7 0

We have such equation
5(4x+6)=6x+9
5*4x+6*5=6x+9
20x+30=6x+9 /-6x
20x-6x+30=6x-6x+9
14x +30=9 /-30
14x=9-30
14x=-21 /:7
2x=-3 /:2
x= $- \frac{3}{2}$ - its the answer

the perimeter of the flower garden is 30 feet. If the width of the flower garden is 3 feet, what is the length?

nadezda [96]

Answer:

12 feet

Step-by-step explanation:

First, you should know that perimeter is equal to the sum of all the sides. If the flower garden is a rectangle, the width on the other side is also 3. 3+3 equals 6. Next, subtract 6 from 30 to get 24. Now, divide 24 by 2 to get the length of 1 side. 24/2 equals 12. So the length is 12 feet
