Well if you download the app photo math and take a photo of it. It will solve it for you
Answer:
x = 29
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
x + 2x + 2 + 3x + 4 = 180, that is
6x + 6 = 180 ( subtract 6 from both sides )
6x = 174 ( divide both sides by 6 )
x = 29
Answer:
Step-by-step explanation:
Add up all the sides to get the perimeter:
3x² -x+4=0
We can use quadratic formula
a=3, b= -1, c=4
The teacher would have to grade 322 problems
14 (problems) x 23 (students)
Answer: 322
