A rectangular blanket for a child that measures 3 feet by 4 feet is made. A border that is exactly 6 square feet is to be created around the blanket. Which TWO equations represent the required width of the border, x?

(3+x)(4+x)=18

(3+2x)(4+2x)=18

(3+x)(4+x)−3(4)=6

(3+2x)(4+2x)=6

(3+2x)(4+2x)−3(4)=6

i dont know it

step-by-step explanation:

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
