X/y=z
if we know x and z
solve for y
x/y=z
times both sides by y
x=zy
divide both sides by z
x/z=y
therefor
(x^4– 3x2 + 4x – 3)/?=(x^2+x-3)
so

=?
solve
first factor them

=?
x^2-x+1=?
the poly is x^2-x+1
Answer:

75 / 5 = 15
Answer:
Step-by-step explanation:
Area of triangle = (1/2)bh

= 270.625 cm²
Area of 6 triangles = 6 * 270.625
= 1623.75 cm²
Trapezium:
a = 25 cm
b = 25 + 12.5 +12.5 = 50 cm
h = 21.65 cm

=811.875 cm²
Area of two trapezium = 2 *811.875
= 1623.75 cm²
Area of star = 1623.75 +1623.75
= 3247.50 cm²
