Answer:
using pythagoras theorem
H^2=P^2+B^2
here h=MN ,opposite(P) be 15 and adjacent(B) be 16
(MN)2=15^2+16^2
(MN)^2=225+256
MN=
MN=21.93
after rounding off MN=21.9

Answer:
1) OPTION D.
2) OPTION D.
Step-by-step explanation:
1) You can calculate the surface area of the rectangular prism with the following formula:

Where w is the width, h is height and l is the length.
The figure show you that:

Then, the surface area is:
![SA=2[(3m*0.5m)+(4m*3m)+(4m*0.5m)]=31m^{2})](https://tex.z-dn.net/?f=SA%3D2%5B%283m%2A0.5m%29%2B%284m%2A3m%29%2B%284m%2A0.5m%29%5D%3D31m%5E%7B2%7D%29)
2) You can calculate volume of the rectangular prism with the following formula:

Where w is the width, h is height and l is the length.
When you substitute values, you obtain the following result:

D
E
F
Work
So the answer to the original problem:
6-4.5 +(-8) equals -1.5
D,E,and F all yeild this answer.
Another way to do it is to simply rearrange the equation
D:
6-4.5 +(-8)
6-4.5-8
your just removing the parenthesis and swapping the sign
E:
6+(-4.5) -8
is the exact same as
6-4.5 +(-8)
you're just moving the parenthesis
F:
This one you're just adding a parenthesis and flipping the of
6-4.5 +(-8)
which turns it into
6+(-4.5)+(-8)
Hope this helps!
<h2>X² + 2x = 4</h2><h2 />
When completing the square, the goal is to create
a perfect square trinomial on the left side of the equation.
The number used to create one will come from
half the coefficient of the middle term squared.
In this case, that's half of 2 squared or 1 squared, which is 1.
So we add 1 to both sides giving us x² + 2x + 1 = 5.
From here, we set this as a binomial squared.
The first term is an x and the second term will
be half the coefficient of the middle term squared.
So we have (x + 1)² = 5.
Now square root both sides and remember to use plus or minus.
So we have x + 1 = ±√5.
Now subtract 1 form both sides to get x = -1 ± √5.
