4x/9
Step-by-step explanation:
1) 8x-13
2)19r-19s
3)8m-10n
Solve in the parentheses then label the ones with the same variable and solve those setting up the equation with variable first. Do check this I am not perfect.
Hope this helped! ;)
Answer:
Scalene
Step-by-step explanation:
With this question, it's best to draw it out or we can use process of elimination.
We can rule out Right as the triangle is already obtuse (it can't be both).
We can rule out Equilateral as all the sides are not equal.
We can also rule out Isosceles as this triangle requires 2 sides to be equal, which clearly, they aren't.
Therefore, we are left with Scalene (C) which is your answer.
A scalene triangle has no identical sides or angles, and can be obtuse, right or acute.

4(3w+5)-2w=70
10w+20=70
10w+20-20=70-20
10w=50
10w/10=50/10
w=5
