Answer:
Step-by-step explanation:
3x + x + 60 = 180.
first, we add the x's together.
4x + 60 = 180
then we see if they all have a common multiple. in this case, they do. they are all divisible by 4, so we can use that.
x + 15 = 45
then, just subtract 15 from both sides, that way we get the variable by itself.
x = 30
also, it is a right triangle. the top angle (3x) multiplied by 3 is 90. any triangle that has a 90 degree angle is automatically a right triangle.
Steps to solve:
-4z + 4 + 12z = 3z + 4 + 5z
~Combine like terms
8z + 4 = 8z + 4
~Subtract 4 to both sides
8z = 8z
~Divide 8 to both sides
0 = 0
All real numbers are solutions.
Set builder notation: {x | R}
This is an identity since every value can be a solution to the equation.
Best of Luck!

<em>3^2 ; Option B</em>
Answer:
the answer is c
Step-by-step explanation:
I took it already i think it's that one .
This is NOT the graph of a function y=f(x). However, if you
solve the original equation for y in terms of x, you can break the graph into
two pieces, each of which is the graph of a function.
The real solution are : x= -4/sqroot7, y= 2/sqroot 7
x= 4/sqroot7, y= -2/sqroot
7
integer solution are: (-1,2) , (1,-2), (1,1)
