Answer:
x = 12
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
3x+19 + 5x = 115
Combine like terms
8x + 19 = 115
Subtract 19 from each side
8x+19 -19 = 115 -19
8x = 96
Divide each side by 8
8x/8 = 96/8
x =12
Answer: 0.6
Step-by-step explanation:
The probability formula to find p(B/A) is :
P(B/A) = p(A n B) / p(B)
Which means that A is contain in B and p(A n B) is p(A)
p(A n B)= p(A)=0.6 × 0.05 = 0.03
p(B)=0.05
Therefore
P(B/A) = p(A n B) / p(B)=p(A) / p(B)
P(B/A)=0.03 / 0.05
P(B/A)=0.6
Since there is no condition whatsoever for this arrangement, I can consider the 2 digits and the 5 letters as 7 different objects.
Total permutation (with no repetition):
7 chosen among 7 , that is 7 ! = 5040 arrangements
Total permutation (WITH REPERTITION):
7⁷ = 823 543

<h3>How to simplify the expression?</h3>
The expression is given as:

Express x^2 - y^2 as (x + y)(x - y) and factorize other expressions

Rewrite the expression as products

Cancel out the common factors

Express 4x^2 - y^2 as (2x - y)(2x + y)

Cancel out the common factors

Take the LCM

Hence, the simplified expression is
and the restriction is
