We need to simpify the given expression. The given expression to us is ,
<u>Given </u><u>Expression</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Using </u><u>Identity</u><u> </u><u>:</u><u>-</u><u> </u>
<u>So </u><u>that</u><u> </u><u>:</u><u>-</u><u> </u>
<u>We </u><u>have</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Hence </u><u>the</u><u> </u><u>required</u><u> answer</u><u> is</u><u> </u><u>-</u><u>1</u><u>/</u><u>4</u><u>. </u>
Answer: 27 times bigger.
Step-by-step explanation:
You need to use the following formula to find the volume of a Square pyramid:

Where "s" is the edge of a side of the square base and "h" is the height of the pyramid.
Knowing that:

You can find the volume of the Pyramid A and the volume of the Pyramid B:

Finally divide the volume of the Pyramid B and the volume of the Pyramid A, in order to find how many times bigger than the Pyramid A is the Pyramid B.
You get:

Answer:
(x+2)²+(y+2)²=36
Step-by-step explanation:
given r=6
center is (-2,-2)
the equation becomes
(x-(-2))²+(y-(-2))² = 6²
on simplifying we get the answer
Answer:

Step-by-step explanation:
8 - 4s = 8 + 13
8 - 4s = 21
4s = 8 - 21
4s = - 13
s = -13/4
