Square root of 75 plus square root of 3
olya-2409 [2.1K]
Answer:
6√3

Explanation:
Before we begin, remember the following:
\sqrt{a*b} = \sqrt{a}  *  \sqrt{b}
m \sqrt{a} + n \sqrt{a}  = (m+n) \sqrt{a}

Now, for the given:
75 can be written as 25*3
This means that:
\sqrt{75} = \sqrt{25*3}
Applying the above concept, we can find that:
\sqrt{75} = \sqrt{25*3} = \sqrt{25}  *  \sqrt{3}
Now, we know that:
√25 = 5 (we ignored the negative value)

This means that:
√75 = 5√3

Finally, we can compute the needed sum as follows:
√75 + √3 = 5√3 + √3 = 6√3

Hope this helps :)

1. (5 pts). A coin is flipped 4 times.
Greeley [361]

Answer:

4/8 or 1/2

Step-by-step explanation:

there are 2 sides of the coin and we flipped it 4 times so 2 x 4 = 8

there are 8 possible outcomes

only 1 side of the coin is face up and we flipped it 4 times so 1 x 4 = 4

so there is a 4/8 (or 1/2 if you want to simplify) chance of flipping a coin four times and landing face up each time.
