The answer is 3x^2 + 6x + 4 (the second one)

Let's start by removing the parenthesis to get 6x + 7 + x^2 + 2x^2 - 3

Then, let's combine like terms (terms with the same variable and exponent) to get 3x^2 + 6x + 4

This is an answer in the multiple choice, so the answer is 3x^2 + 6x + 4 (the second one)

A ladder is leaning against a building and makes 28 degree angle with the ground.

Dominik [7]

To solve this problem you must apply the proccedure shown below:

1- You have that the laddder makes an angle of $28 degrees$ with the ground and the top of the ladder reaches $35ft$ .

2- Therefore, you have:

$Sin\alpha =\frac{opposite}{hypotenuse}$

Where:

$opposite=35\\ hypotenuse=length\\ \alpha =28degrees$

3-You must substitute values and solve for the lenght, as following:

$Sin(28)=\frac{35}{lenght} \\lenght=\frac{35}{Sin(28)} \\ lenght=75ft$

Therefore, the answer is: $75ft$
