Answer:
715.6 in^3
Step-by-step explanation:
<u>Step 1:</u>
multi. 10x6x8
=480
<u>Step 2:</u>
v=1/2 xPIE (5)^2 x6
= 235.6
<u>Step 3:</u>
480 + 235.6
= 715.6
To simplify 4/(2+7i), we multiply it by a fraction equal to one that removes the i value in the denominator. The best value to do this is the complex conjugate divided by itself, so we have 4(2-7i)/((2+7i)(2-7i)). Simplifying, we have (8-28i)/(4-(-49))=(8-28i)/53, which is a completely simplified fraction since 8 and 53 are relatively prime (or coprime), and there are no radicals in the denominator.
(3x − 5) − (4x + 6)
to simplify combine like terms
= (3x - 4x) + (-5 - 6)
= -1x - 11 (same as -x - 11)
ANSWER: -1x - 11 (first choice)
