Answer:
5i![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
Step-by-step explanation:
Using the rule of radicals
×
⇔ ![\sqrt{ab}](https://tex.z-dn.net/?f=%5Csqrt%7Bab%7D)
and
= i
Given
![\sqrt{-75}](https://tex.z-dn.net/?f=%5Csqrt%7B-75%7D)
= ![\sqrt{25(3)(-1)}](https://tex.z-dn.net/?f=%5Csqrt%7B25%283%29%28-1%29%7D)
=
×
× ![\sqrt{-1}](https://tex.z-dn.net/?f=%5Csqrt%7B-1%7D)
= 5 ×
× i
= 5i
Using the combination formula, and considering that the list has 6 ingredients, it is found that 20 groups of 3 different ingredients can go on a taco.
The order in which the ingredients are chosen is not important, hence, the <em>combination formula</em> is used to solve this question.
<h3>Combination formula:
</h3>
is the number of different combinations of x objects from a set of n elements, given by:
In this problem, 3 ingredients are chosen from a set of 6, hence:
![C_{6,3} = \frac{6!}{3!3!} = 20](https://tex.z-dn.net/?f=C_%7B6%2C3%7D%20%3D%20%5Cfrac%7B6%21%7D%7B3%213%21%7D%20%3D%2020)
20 groups of 3 different ingredients can go on a taco.

Answer:
Undefined
<em>Step </em><em>by</em><em> step</em><em> </em><em>explaination:</em>
<em> </em>
by order of operations we know that we multiply first;
so, 0x-(7*9)=0
1) Multiply the ones in brackets first:
0x-63=0
2) To make X the subject perform the opposite operation:
0x-64+63=0+63
0x=63
3) Divide 0 on both sides;
0x/0= 63/0
therefore; <u>x is undefined</u>
Answer:
4.) 12ft
Step-by-step explanation:
You solve the area of a square using the following equation:
Area of a square = <em>s</em>²
Plug in 144 for Area of a square:
144 = s²
Isolate the variable, s. Root both sides of the equation.
√144 = √s²
s = √144 = √(12 * 12) = 12
4.) 12ft is your answer.
