A=1/2B*3B make b the subject of the formula​

                  2A

or b = √

                    3

Step-by-step explanation:

A = (1/2)B·3B becomes (3/2)·b^2.  Solve this for b:

Taking the square root of both sides, we get:

√A = √(3/2)·b, so that

√A

√(3/2)

             2A

b = √ ( )

               3

i'm not sure i quite understand, could you provide more information?

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
