5x15, 3x25 because 30+45=75 and both 5x15 and 3x25 equal 75
x^2 + 4x + 3 + 1 = (x + 2)^2
So 1 need to be added.
Should be 3.3125. Hope this helps
Answer:
5.83 = CD
Step-by-step explanation:
We can use the pythagorean theorem to solve
The legs are the x and y distances
x = (1- -4) = 5 units and y = 3 units
a^2+ b^2 = c^2
5^2 + 3^2 = c^2
25+9 = c^2
34 = c^2
Taking the square root of each side
sqrt(34) = c which is the distance from C to D
5.830951895 = CD
5.83 = CD
