Answer:

x = 8

Step-by-step explanation:

We can use PEMDAS to solve algebraic equations:

Parentheses

Exponents

Multiplication/Division

Addition/Subtraction

First, we have parentheses in this equation, so distribute

3(11x) + 3(5) = 279

Next, because there are no exponents, multiply

33x + 15 = 279

To isolate x, subtract 15 from both sides

33x + 15 - 15 = 279 - 15

33x = 264

Then divide both sides by 33

x = 8

Help needed! no links please, they're annoying.

The area of a rectangle is length*width.

The length of this 3x and the width is 2x-3. This means that, to find the area, you need to multiply 3x and 2x-3.

Start by writing out this equation:
A=l*w

Then, plug in your given values:
A= 3x*2x-3 (you can also write it as A= 3*x*2*x-3)

Then, following the order of operations, you start by multiplying. This makes your equation become A = 6x^2 -3. (^2 means squared). It turns into this because 3 * 2 is 6 and x * x is x^2 and you still haven’t used the 3 yet.

After this, there is nothing more that you can do to simplify the equation. Therefore, the area is 6x^2 - 3.

I hope this helped!
