Answer:
The second one; x²+7x+12
Step-by-step explanation:
So, since the beginning lengths of the square is x and x, the area of the square is x².
But then, you add 3 to one length, so that side is now (x+3), and then you add 4 to the width, so that is now (x+4).
Finally, you would multiply them together to get the equation you would use to find the new area.
For this, you would cross-multiply everything together; the x in the length by the x in the width, the x in the length by the 4 in the width, the 3 in the length by the x in the width, and then the 3 in the length by the 4 in the width. Now, all you have to do is add all of these together to get your answer.
Here's the work:
Answer:
1 liter per hour (1.025)
Step-by-step explanation:
If you want to find the rate of production, simply divide 4.1 by 4
you should get 1.025 but a rounded equivalent would be 1
I think it would be 84 + 0.45m + 108.
Which simplified could be 0.45m + 192. Hope it helps! :)
sin²x sec²x +1 = tan²x cosec²x is an Identity and therefore Option C is an Identity.
<h3>What is a Trigonometric Identity ?</h3>
Trigonometric Identities are based on Trigonometric ratios , these are useful in conversion of the ratios into each other and to solve the problems of Trigonometry.
There are four Identities Given
Among them Option C is an Identity because on solving it
sin²x sec²x +1 = tan²x cosec²x
(sin²x/cos²x) +1 = sin²x / (sin²x cos²x)
sin²x +cos²x = 1
Which is an Identity and
therefore Option C is an Identity.
