It equals 2.25 because you multiple 2 and 9 and then divide the answer by 2.
area would be 200.86 or 200.9 if you are rounding to the nearest tenth.
If the discriminant is negative no real solution exists.
If the discriminant is equal to 0 only one real solution exists.
If the discriminant is positive 2 real solutions exist.
The discriminant:
D = b² - 4 a c
1 ) - 7 x² + 6 x + 3 = 0
D = 6² - 4 · ( - 7 ) · 3 = 36 + 84 = 120 > 0
Answer: b) two solutions
2 ) - 8 x² - 8 x - 2 = 0
D = ( - 8 )² - 4 · ( - 8 ) · ( - 2 ) = 64 - 64 = 0
Answer: a ) one solution
Answer:

Step-by-step explanation:
there is 2 possible answers
There are 13 almonds and 9 walnuts per bag so that’s 13+9=22 nuts per bag.
If there are x bags then the number of nuts is 22x.
Assuming y is the total number of nuts we get y=22x
