To solve first move the 98 to the other side by subtracting it from both sides. Then divide by - 1 on both sides to that the x^2 is no longer a negative. You are left with:

Now square root both sides to get

The two factors that make up 98 are 49 and 2. 49 can be square rooted. So we are left with these answers:

and
I think the answer is ;B.316 and 38
Answer:
See like terms have the same variables
E.g 2x+4y-x+7y
We should take the same variable together with the same signs so here
2x-x will be 1x
4y+7y will be 11 y
So x+11y

Answer:
B) option 40°
Step-by-step explanation:
It is an isosceles triangle
Angle 1 and angle 2 add up to :
180 - 100 = 80°
you divide into two equal parts
80/2 = 40°
Angle 1 = Angle 2 = 40°
Hope this helps
