Answer:
p^2 + q^2 = 22/9.
Step-by-step explanation:
For a quadratic function ax^2 + bx + c if the zeroes are A and B then
A + B = -b/a and AB = c/a.
2x^2 - 7x + 3
Now p and q are the zeroes of the above function so
p + q = 7/3 and pq = 3/2.
Now p^2 + q^2 = (p + q)^2 - 2pq
= (7/3)^2 - 2* 3/2
= 49/9 - 3
= 49/4 - 27/9
= 22/9.
I know for a fact B is wrong, so you can mark that off. I got C.
Answer:
yes; SAS (Side Angle Side)
Step-by-step explanation:
if you divide all sides by three they come out as the same numbers as the left triangle and they are both the same type of triangle
When you are solving an algebraic one-step equation, the goal is to isolate the variable on one side of the equal sign, two-step equations are the same, but with one more step (hence the name)
