Marla is making a fence to go
all the way around the small
Flower garden she planted. The
garden is 5 feet long and 3 feet
wide. How many feet of fencing
does she need?

16 feet of fencing

Step-by-step explanation:

This equation is essentially asking us the perimeter of the fence. If you add 5+3+5+3 you get the sum of 16

16 feet

Step-by-step explanation:

She will need to the same amount of fencing as the measurement of her perimeter. To calculate the perimeter, you add length times 2 plus width times 2. 5x2+3x2=16, so the perimeter of the garden is 16 feet meaning she will need 16 feet of fencing :)

step-by-step explanation:

i hope this : )

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
