Answer:
-5+5r-2 -->
--> 5r-7 <--
Explanation --
Distribute from the parentheses, of course excluding the -2 because it isn't involved, and you'll get --> -5 + 5r -2
Simplify by putting the like terms together (subtract) -->
5r -7 (you get -7 by doing -5-2, and you leave 5r by itself since it doesn't have anything more to simplify with or has any other like term)
So, the final, simplified answer -->
5r-7
Hope this helps!! Have a nice day! :)
Answer:
x = 128 degrees
Step-by-step explanation:
First figure out the angle inside the triangle
1st step: add 55 and 73 together:
⇒ 55 + 73 = 128
2nd step: subtract the sum from 180:
⇒ 180 - 128 = 52
to find x, take 180 again and then subtract 52 from it:
⇒ 180 - 52 = 128
<em>I believe the exponential form above is 5.61 x </em>
Answer:
561
Step-by-step explanation:
A<em> "scientific notation"</em> is being used in order to express large numbers in its <u>simplest form</u>. This is commonly used in careers that use Mathematics very often like<em> engineers</em> or<em> scientists </em>because it makes their computation easier.
The<em> "standard form"</em> refers to the standard or traditional way of writing the numbers.
In order to get the standard form above, you have to check the <em>"power of the number 10." </em>The exponent above is 2. This means that you have to move the decimal point of 5.61 to the<em> right twice.</em> So, the answer is 561.
as the product of 90 degrees and 20 degrees
30x60=1800
90x20=1800
