Answer:
x = 8
Step-by-step explanation:
7x + 2(6x + 9) = 170
2(6x + 9) = 12x + 18
7x + 12x + 18 = 170
19x = 152
152/19 = 8
x = 8
Answer:
Scalene triangle as there are no sides given.
or,

Scalene triangle = No sides are equal.
Isosceles triangle = 2 sides equal.
Equilateral triangle = All sides equal.
Right angled triangle = One angle is 90.
Since, the picture hasn't given any sides, i am gonna say it's a scalene triangle.
If, the triangle is for measure, measure it using a ruler and classify it based on the result.

Ok so Jesse is 10-15%
Margie is <10%
Pietro is >15%
Susana is 10%-15%
And I think Raul maybe >15%
Basically you can determine how far off they are by doing the number they guessed divided by the actual number (132) so for Jesse I did 120/132 and I got .909 and so on. Just take the two numbers after the decimal and that’s your percent. So the .909 is about 90% so now do 100% (of the 132) - 90 and you get 10. So I put 10%-15%
