Answer:
its A
Step-by-step explanation:
When you have something like this, all you need to do is substitute the values, the last is for what value of x
For the first one;
((x^2+1)+(x-2))(2)
(x^2+x-1)(2)
(2)^2+(2)-1
4+2-1
5
For the second one;
((x^2+1)-(x-2))(3)
(x^2-x+3)(3)
(3)^2-(3)+3
9-3+3
9
For the last one;
3(x^2+1)(7)+2(x-2)(3)
3((7)^2+7)+2((3)-2)
3(49+7)+2(3-2)
3(56)+2(1)
168+2
170
Answer:
The point of intersection with the x axis are (-2,0) and (8,0)
Step-by-step explanation:
given circle equation x²+y² = 25
x² + y² = r²
r is the radius.
✓(25) = 5
given the center is at (3,0) and radius of 5
(3+5,0) and (3-5,0)
(8,0) and (-2,0)
