Im assuming the problem is x^2-16, which would be factored to (x-4)(x+4)
D, it’s a function because the Y and X values have its own numbers , and vertical are functions . Horizontal is not a function
Answer:
D. If a shape is an equilateral triangle, then it is an isosceles triangle.
Step-by-step explanation:
I would help you but I don’t know
Step-by-step explanation:
x + y = 24 where x and y are the 2 parts of diagonal Other diagonal wil be smaller that 24.
x^2 + z^2 = 13^2
y^2 + z^2 = 20^2 where z = 0.5 * length of smaller diagonal)
form last 2 equations
y^2 - x^2 = 20^2 - 13^2 = 231
now y = 24-x so we have
(24 - x)^2 - x^2 = 231
576 - 48x = 231
48x = 345
x = 7.1875
z^2 = 13^2 - 7.1875^2 = 117.34
z = 1.83
so smaller diagonal = 21.66 cm
looks like its the third choice.
