Find the x and y intercept of y= -2(x-3)^2+4
Neko [114]
Y intercept occurs when x = o  so it is  -2(0-3) + 4  =   -2

x intercepts:-

-2(x - 3)^2  + 4 = 0
 
(x - 3)^2  = -4/-2 = 2

x - 3 = +/- sqrt2

x = 3 + sqrt2 and 3- sqrt2

Simplify the expression below. (2n/6n+4)(3n+2/3n-2)What is the numerator of the simplified expression?
photoshop1234 [79]
(2n/6n+4)(3n+2/3n-2)
=2n(3n+2)/(6n+4)(3n-2)
=(6n^2 + 4n)/(18n^2 - 12n + 12n -8)
=(6n^2 + 4n)/(18n^2 - 8)
=2(3n^2 + 2n)/2(9n^2 - 4)
=(3n^2 + 2n)/(9n^2 - 4)
=n(3n+ 2)/(3^2 × n^2 - 2^2)
=n(3n+ 2)/(3n-2)(3n+2)
=n/(3n-2)
Answer:The numerator of the simplified expressions is n.

A triangle has side lengths of 14 cm and 7 cm. Which could be the value of the third side, 22 cm or 20 cm?
Eddi Din [679]

Answer:

Undefined, it can be 20 cm, 22 cm or any value.A triangle has no limitations for any of each three sides.

Step-by-step explanation:

How it works? The triangles have no limits on their sides, but by their angles. Each triangle sums 180 degrees at the inner angles. If you don't have specific values for the angles it is not necessary to get some values for the third side. It could be 1, 2, .... or even 1000.
