Answer:
(x + 5) (x^2 -3)
Step-by-step explanation:
Do the grouping:
Then factor out 
in the first and −3 in the second group.
Factor out the common term x + 5 by using the distributive property.
Polynomial 
is not factored in since it does not have any rational roots, thus getting the following:
Answer:
Hi there!
The correct answer is: (x+8)² = 73
Step-by-step explanation:
First you want to modify the equation: x² + 16x - 6 = 3 into x² + 16x = 9 by adding 6 on both sides.
Then you analyze the new equation, if you can see, 16x is positive which means two positive numbers have to be added up to equal a positive. Which eliminates the choices that have (x-8)²
And now you are left with two choices:
(x+8)² =73 and (x+8)² = -55
Now remember, when you factor out (x+8)² it equals to x² + 16x + 64
next let's bring it back to the very first equation: x² + 16x = 9
now which choice matches the result x² + 16x = 9. The answer will be (x+8)² = 73 because when you subtract 64 on both sides you get 9.
24x - 16 is the answer!
Explanation:
Area of a rectangle = length x breadth
Therefore, Area of the given rectangle will be; 8 (3x-2)
= 24x - 16.
Volumn = LWH
small rectangle = 5 x 5 x 12 = 300 sq yds
Larger rectangle = 4 x 12 x 18 = 864 sq yds
