I cant directly give u the answer but here is some help:
for part a add up and solve the equazions on the whiteboard.
for part b subtract 90 from what you got from part a.
Hope this helps. Sorry i couldnt help more.
I'm pretty sure its B. (9x2+2x-7)(x)+(9x2+2x-7)(-4)
Because its just splitting up the (x-4) and if you add the answers together then you get the same answer as the original<span />
Answer:
i think the answers 5
Step-by-step explanation:
Answer:
probability is 0.67
Step-by-step explanation:
We know that Angle in a circle = 360°
Area of total shaded parts = 60 + 60 = 120°
Area of total unshaded parts = 360-120 = 240°
Probability that a random selected point within the circle falls in the unshaded area
= 240/360
= 2/3= 0.67
b and d can be eliminated because there are multiple solutions.
answer: A, because it shows all solutions to the equation
