The general formula of a pyramid with any base is 1/3 bh where b is the area of the base and h is the height. In this case, the height of the pyramid is said to be twice the height of the prism, h. Hence the area becomes 1/3 b*2h or equal to option A. 2/3 bh
If you want to solve the equation -5 - (15 * y - 1) = 2 * (7 * y - 16) - y, you can calculate this using the following steps:
-5 - (15 * y - 1) = 2 * (7 * y - 16) - y
-5 - 15 * y + 1 = 14 * y - 32 - y
-5 + 1 + 32 = 14 * y - y + 15 * y
28 = 28 * y /28
y = 1
The result is 1.
Hello :
by moivre theorem :
[2(cos15*+isin15*)]^3 = 2^3(cos(3×45*)+isin(3×45*))
=8 (cos45*+isin45*)
= 8 ( √2/2 +i √2/2)
= 4√2 + 4√2 i ..... ( <span>in standard form a+bi)
</span>a = b = 4√2
(X x 6) = (X x 8) -4
Ps. Make sure yoi dont times the (X x 8) by -4 the -4 is by itself.
I personally found it easier thinking if there is a difference of 4 between 6 x X and 8x X then it must be 2x2 as the difference between 6 and 8 is 2. therefore 4 divided by 2 = 2 and 2 x 2 = 4
Therefore x = 2
