= 3a^2b(cuberoot(b^2)) - 3a^2b^3(square root(3a))
answer is the first choice
<span>Differentiating :
y' = 1 + sec^2(x),
</span><span>
cosπ=−1</span><span>
plug in pi = -1 ,for x:
1 + sec^2(pi) = 1 + (-1)^2
= 2</span>
Answer:
if you are subtracting then you would : 457-418=39
Answer: B. -27+452i
Step-by-step explanation: Simplify the real and imaginary parts of the expression.
Hope this helps you out.
Answer:
5 ft
Step-by-step explanation:
If all sides are of the same length, we can multiply the value of one side by 3, because a triangle has three sides (and the perimeter is all sides added together), to find the perimeter.
× 3
can be rewritten as
, so:
× 

The numerator & denominator share a common factor of 3, so:
5 ft is the final answer/perimeter.
hope this helps!
