First off, remember that finding the x-intercepts means setting y equal to zero and solving for the x-values, so this question is really asking you to "Solve 4x2 – 2x – 5 = 0".
Now, let's start the completing-the-square process. To begin, we have the original equation (or, if we had to solve first for "= 0", the "equals zero" form of the equation). In this case, we were asked for the x-intercepts of a quadratic function, which meant that we set the function equal to zero
Answer:
2x+10+x+5=180
3x+15=180
3x=165
x=55
hope this helps
have a good day :)
Step-by-step explanation:
Im sorry if this is wrong but i think it is c
It is a because look at the x-axis and I also had that for homework.
