Answer: That is false
Step-by-step explanation: 9 is odd but not prime
I don't like these algebra problems which pretend to be geometry.
These are supplementary angles adding to 180 degrees; geometry done.
7x - 1 + 3x - 9 = 180
10 x = 190
x = 19
ABC=3x - 9 = 3(19) - 9 = 48
Answer 48°
The base of given triangle is 8 cm.
Further explanation:
The area of triangle is calculated by using two methods
- Hero's formula
- Base and Height
Hero's formula requires all three sides of triangle while we can use only base and height in second formula.
Given
As the area of triangle and height are given, then
The base of given triangle is 8 cm.

Answer:
n + 6
Step-by-step explanation:
5n - 3 ( n - 2 ) - n
4n - 3 ( n -2 )
4n - 3n - 3 x (2)
4n - 3n - 3 x 2
4n - 3n + 6
n + 6
