Answer:
33
Step-by-step explanation:
first you set up the problem, supplementary angles equal 180 degrees so the equation should look like, 4x+x+15=180. then you solve from there by combining like terms and you should get x equal to 33
Answer:
solution is

Step-by-step explanation:
We are given equation as

Firstly, we will find equations
First equation is

Second equation is

now, we can draw graph
and then we can find intersection point
we can see that
intersection point is (1.353,1.613)
so, solution is

-3^2= -(3)^2
The exponent of 2 only applies to the number 3. -(3)^2 should equal -9. This is true because according to the order of operations, exponents should be evaluated before multiplication. The negative sign here represents -1* 3^2.
If you want to find -3 to the power of 2 it must be written (-3)^2.
