Answer:
i thought i had the answer but then i got it wrong im sorry
Step-by-step explanation:
(2x^2 + 4x + 6) - (-3x - 5x^2 + 4)
The negative sign separating the expressions is just multiplying the rightmost expression by -1.
(2x^2 + 4x + 6) + (3x + 5x^2 - 4)
Now, let's add together terms that share the same variable.
2x^2 + 5x^2 = 7x^2
4x + 3x = 7x
6 + (-4) = 2
Let's combine each of these terms into one expression.
7x^2 + 7x + 2 is the final answer.
2 1/4 * 2
9/4 * 2 = 18/4
4 1/2

The distance from building A to building C is 433m
<h3>Right angle triangle:</h3>
- A right angle triangle has one of its angle as 90 degrees. The sides can be found using trigonometric ratios.
Therefore,
sin 60° = opposite / hypotenuse
sin 60° = b / 500
cross multiply
b = 500 sin 60°
b = 500 × 0.86602540378
b = 433.0127
b = 433 meters
