15p+15p+25p=30p+25p=55p
To solve the equation for x, first, we add 16 from both sides of the equation:

Now, we divide by 6:

Finally, we get that:

Answer:
The answer is c because every quadrilateral adds up to 360 so when you add all the numbers you get 290 and when you subtract 360-290 is 70.
(5,12,13) is a right triangle and can be constructed.
All the others do not satisfy the triangle inequality, i.e. the sum of two short sides must exceed the long side in order for the triangle to be constructed.
Examples:
2+11<15, so no
3+7<11, so no
4+8<15, so no
but 5+12>13 so yes, it can be constructed.
Answer:
is thier any way you can take a picture of what the problem is cause alot of the equation are not adding up the way you put them
