Answer:
1. two square root of ten
Step-by-step explanation:
Given expression is:
![\[\sqrt{5}* \sqrt{8}\]](https://tex.z-dn.net/?f=%5C%5B%5Csqrt%7B5%7D%2A%20%5Csqrt%7B8%7D%5C%5D)
Simplifying the expression:
![\[\sqrt{5}* \sqrt{4 \ast 2}\]](https://tex.z-dn.net/?f=%5C%5B%5Csqrt%7B5%7D%2A%20%5Csqrt%7B4%20%5Cast%202%7D%5C%5D)
= ![\[\sqrt{5}* \sqrt{4}*\sqrt{2}\]](https://tex.z-dn.net/?f=%5C%5B%5Csqrt%7B5%7D%2A%20%5Csqrt%7B4%7D%2A%5Csqrt%7B2%7D%5C%5D)
= ![\[\sqrt{5}* 2*\sqrt{2}\]](https://tex.z-dn.net/?f=%5C%5B%5Csqrt%7B5%7D%2A%202%2A%5Csqrt%7B2%7D%5C%5D)
= ![\[2 * \sqrt{5} * \sqrt{2}\]](https://tex.z-dn.net/?f=%5C%5B2%20%2A%20%5Csqrt%7B5%7D%20%2A%20%5Csqrt%7B2%7D%5C%5D)
= ![\[2 * \sqrt{10}\]](https://tex.z-dn.net/?f=%5C%5B2%20%2A%20%5Csqrt%7B10%7D%5C%5D)
So among the given options, option 1 is the correct one,namely, two square root of ten.
To simplify the expression stated, it is better to write it in the numerical form. The statement is:
<span>quantity 12 x plus 36 over quantity x squared minus 4 x minus 21
The numerical form is:
12x+36 / (x</span>²-4x-21)
Simplifying,
12x+36 / (x<span>²-4x-21)
</span>12 (x+3) / (x+3)(x-7)
We can cancel the x+3 term, leaving only:
12/(x-<span>7)</span>
Answer:
Your x-intercepts are -(3, 0) and (4, 0).
Step-by-step explanation:
This question makes no sense. If Karl only has 5 pounds of flour and each batch of cookies uses 13 pounds of flour, then he doesn’t even have enough to make 1 batch of cookies let alone 7 batches.
A fair die has 6 sides so a 1/6 chance for each number
So divide 480/6= 80
80 times for each number, 80 for 6
