Answer:

Step-by-step explanation:
Here we are going to apply the rule of "Square of the difference". The rule is as given below
---------(A)
Now we have our original polynomial as

Which can be re written as
---------------(B)
Hence comparing it with (A)

Applying the rule on (B)

Hence our answer is

Answer:
4x + 36
Step-by-step explanation:
combine like terms
3x + x = 4x
2 + 34 = 36
4x + 36 Is the full answer
Answer:
see explanation
Step-by-step explanation:
The angle at the circumference b , is half the angle subtended at the centre by the arc XZ, that is
b = 0.5 × 72 = 36
OZ and OX are congruent ( both radii of the circle )
Thus Δ OXZ is isosceles with base angles congruent, thus
a =
=
= 54
∠ XZY = 90° ( angle in a semicircle is right )
