Answer:
15 out of 25, 60%, and 15/25
Answer:
A
Step-by-step explanation:
3x^2 - 8x + 4 = 0
x= [-b +or- square root (b^2 - 4ac)] ÷ 2a
= [-(-8) +or- square root (-8)^2 - 4(3)(4)] ÷ 2(3)
= [8 +or- square root 16] ÷ 6
= 2 or 2/3
It would be A because the r is being distributed to both the a and the b
80. this is bc the triangle must add up to 180 and 60+40=100
