Question

Need urgent help in math please!!

please help find answer, and explain how you got it! (solution) thank u!!

Answer 1

24x^2+20x+4

Explanation:

Area is length times width.

The length is (8x+4) and the width is (3x+1).

If we follow the formula for the area of a rectangle, then it would be

(8x+4)(3x+1).

Next, you would foil.

Take the first and multiply it by the second equation as follows

8x*3x+8x*1 which would give you

24x^2+8x

Then, you would take the second from the first equation and multiply it with the second equation as well.

4*3x+4*1 which would give you

12x+4

Combine all of it together

24x^2+8x+12x+4

Combine like terms

24x^2+20x+4

That's the area.

Hope this helps.

Answer 2

Answer: 24x² + 20x + 4

Explanation:

Area of a rectangle can be found with A = L * W;

A = L * W

A = (8x + 4) * (3x + 1)

Now we can use the "FOIL" method, which is used to multiply binomials.

[F] First ➜ 8x * 3x = 24x²

[O] Outside ➜ 8x * 1 = 8x

[I] Inside ➜ 4 * 3x = 12x

[L] Last ➜ 4 * 1 = 4

Lastly, we add it all together for our final answer.

24x² + 8x + 12x + 4 = 24x² + 20x + 4
