Answer:

= 4sqrt3

Step-by-step explanation:

-2i sqrt -12

= -2i * i sqrt12 <-- i^2 = -1

= -2i^2sqrt12

= -2(-1)sqrt12

= 2sqrt12

= 2 * 2 sqrt3

What information is found in the left column of a two column proof?
cupoosta [38]
The left column is for statements and the right column is for reasons which justify the corresponding statement. 

Answer: C) Statements

A statement is simply a sentence with words and/or math expression. For example, one statement could be "Segment AB is parallel to segment CD". That same statement can be translated to "AB || CD". The two vertical lines indicate "parallel".

Christina wants to buy some miniature goldfish. She reads that a 9-gallon aquarium is the
Ronch [10]

Based on the image attached of the graph, the points that show equivalent ratios that would also be on the graph are option A and D which are: (6,18)  (1,3).

<h3>What is the graph about?</h3>

Note that: \frac{x}{y}

=\frac{3}{9}

= 1/3

So when you use 1/3 to compare all the options given, you will see that only option A and D  is equal to the value given.

So if a person can write that  we got  1 fish and we needs 3 gallons and when a person  make a point on the line, it will be (1,3).

The other equivalent fraction is known to be 6/18. When a person multiply the numerator and denominator by 2, the value that will be obtained is:

\frac{3 x 2 }{9 x 2}   = 6/18.

So therefore, Based on the image attached of the graph, the points that show equivalent ratios that would also be on the graph are option A and D which are: (6,18)  (1,3).

Jessica assembles a product that requires the insertion of 3 aluminum pins. She can assemble approximately 15 products per hour.
larisa [96]
If she can make 15 per hour that would mean that each hour she is making 15 cans.

She has 6 hours that means that she will make 90 products.

How To Do The Math: 15<span>×6=90

Since we are finding out how many pins she need and not haw many products we will have to check how many pins she will need per product.

She needs 3 pins per product.

Since she will be making 90 products all we have to do is multiply 90 by 3 which will equal 270.

How To Do The Math:90</span><span>×3=270

Your Answer will be 270 Pins.</span>
