What values of b satisfy 3(26 + 3)² = 36?
MakcuM [25]

The numeric value of the b is 0.23 which satisfy the given equation.

According to the statement

We have to find that the value of the b.

So, For this purpose, we know that the

The numeric value refers to the worth of each digit depending on where it lies in the number.

From the given information:

The equation is a

3(2b + 3)² = 36

then to find the value of b rearrange the terms then

(2b + 3)² = 12

(2b + 3) =  \sqrt{12}

(2b) =   \sqrt{12}  -3

then

b  = \sqrt{12}  -3/ 2

b = 3.46 - 3/2

b = 0.46/2

b = 0.23.

So, The numeric value of the b is 0.23 which satisfy the given equation.

The graph shows two lines, A and B.
jeka94

When working with two equations (aka a system of equations), the solution is (or the solutions are) where the graphs intersect.  

If they intersect once, there's one solution.  

If they intersect twice, there are two solutions.

The solution IS the point(s) of intersection.  

Every point on a line is also a solution to the equation that makes the line.  Since that interseciton point is on both lines, it's a solution for both lines.
