Answer:

Simplifying

ax + b = 2x + 3

Reorder the terms:

ax + b = 3 + 2x

Solving

ax + b = 3 + 2x

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-1b' to each side of the equation.

ax + b + -1b = 3 + -1b + 2x

Combine like terms: b + -1b = 0

ax + 0 = 3 + -1b + 2x

ax = 3 + -1b + 2x

Divide each side by 'x'.

a = 3x-1 + -1bx-1 + 2

Simplifying

a = 3x-1 + -1bx-1 + 2

Reorder the terms:

a = 2 + -1bx-1 + 3x-1

What is the square root of 49 multiplied by the square root of 9

fiasKO [112]

First we need to find the the answer to both the square root of 49 and 9.

The "square root" is a term referring to a number, multiplied by itself (x • x) would be = to your square root.

So for example: Square root of 16 = 4 because 4*4=16

So lets get out numbers:

$\sqrt{9} =3
$
$\sqrt{49}=7$

Now you multiply 3*7 (or 7*3) and you get 21.

Final answer: 21
