Answer:
The value of P(AUB) = 0.72
Step-by-step explanation:
As
We can determine the value of P(A∩B) Using the formula
P(AUB) = P(A) + P(B) - P(A∩B)
= 0.6 + 0.3 - 0.18
= 0.72
Therefore, the value of P(AUB) = 0.72

The description below proves that the perpendicular drawn from the vertex angle to the base bisect the vertex angle and base.
<h3>How to prove an Isosceles Triangle?</h3>
Let ABC be an isosceles triangle such that AB = AC.
Let AD be the bisector of ∠A.
We want to prove that BD=DC
In △ABD & △ACD
AB = AC(Thus, △ABC is an isosceles triangle)
∠BAD =∠CAD(Because AD is the bisector of ∠A)
AD = AD(Common sides)
By SAS Congruency, we have;
△ABD ≅ △ACD
By corresponding parts of congruent triangles, we can say that; BD=DC
Thus, this proves that the perpendicular drawn from the vertex angle to the base bisect the vertex angle and base.

Answer:
x=1
Step-by-step explanation:
We can solve this equation using a mix of simplifying and using arithmetic on both sides:
6-4x=7x-9x+4
6-4x=-2x+4
2-4x=-2x
2=2x
1=x
x=1
