How do you simplify 2√5+3√5-√5

aalyn [17]

We can simplify 2√5+3√5-√5 because they all have the same radical, √5. Now that we know this, we can imagine that there are no radicals, and that we are just adding numbers. This results in our expression being 2 + 3 - 1. This gives an answer of 4. Finally, we add the √5 to the 4 to get 4√5.

What are the solution

AleksandrR [38]

Answer:

Step-by-step explanation:

We can get two equations from the inequality:

$3x+2>9\\3x+2>-9$

We just need to simplify both equations to get our answers:

$3x+2>9\\3x>7\\x>\frac{7}{3}$

$3x+2>-9\\3x>-11\\x>\frac{-11}{3}$

The two answers we get are:

$x\frac{7}{3}$

Which is also B.

The function f(x) = −x^2 − 5x + 50 shows the relationship between the vertical distance of a diver from a pool's surface f(x), i

elena-14-01-66 [18.8K]

We will solve the equation to find a zero of f(x): $-x^{2}-5x+50=0$
The formula is: $x_{12} = \frac{-b\pm \sqrt{b^{2}-4ac } }{2a}$ where:
a=-1, b=-5, c =50 $x_{12} = \frac{5\pm \sqrt{25+200} }{-2}= \frac{5\pm \sqrt{225} }{-2}= \frac{-10}{-2}=5$ This is the only solution because the other is: $\frac{5+10}{-2}= \frac{15}{-2}=-7.5$ which is not possible.
Answer: D) The diver hits the water 5 feet away horizontally from the board.
