It should be 7.8 which is answer D
If - 1 is a zero then
is a factor.
Dividing with this factor using the long division approach, we get the quadratic factor to be,
(see attachment).
We can rewrite the polynomial as
We can further factor as
That is
Answer:
73*-2 =-146 you have to multiply the 73 to the -2
Step-by-step explanation:
4x^2-25= (2x)^2-5^2=(2x-5)(2x+5)
Used: a^2-b^2=(a+b)(a-b)
Answer:
3
Step-by-step explanation:
P is the in-center
⇒PA=PE=PD because they are in-radius of the in-circle
We know that, tangent segments drawn from a point outside the circle are always equal in length
⇒DK=EK=7.2
In right triangle PKE,
using Pythagoras' Theorem :
⇒
⇒
⇒
⇒
Therefore,
