C and E, evaluate the numbers outside of the parenthesis to the inside
The answer is A I believe
<span>for finding the value, as follows is the method:
in 15th of march,his bank showing a balance of $56.75.in March 20, it was $87.37 (after 5 days)
$87.37 -$56.75.=$30.62, and $30.62+$5+$13.5=$48.87. Carlos deposited in his account between the March 15 and the March 20 the amount of $48.87. So the answer is the choice B.</span>
<span>The perimeter is 14.47
Since you have 3 vertices, the polygon you have is a triangle. The sides of the triangle will be XY, XZ, and YZ. Just use the pythagorean theorem to calculate the length of each side and then add the lengths together for the result.
Side XY = sqrt( (-1-3)^2 + (3-0)^2) = sqrt(16+9) = sqrt(25) = 5
Side XZ = sqrt ( (-1-(-1))^2 + (3-(-2))^2) = sqrt(0+25) = sqrt(25) = 5
Side YZ = sqrt( (3-(-1))^2 + (0-(-2))^2) = sqrt(16 + 4) = sqrt(20) = 4.47
Now add the length of each side together
5 + 5 + 4.47 = 14.47</span>
