A ractangular cornfeild has a length of 7kilometers and an area of 63 square kilometers. A. What is the widith of the cornfeild?
B. What will be the area of the length and width are doubled?

A. 9

B. 252

Step-by-step explanation:

A. 63 divided by 7 = 9.

B. 7x2=14

9x2=18

14x18=252

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
