Conclusion: if 188 students take the exam, then 188·0.84=157.92 (157) would receive a score above 80
Step-by-step explanation:
u know u can download math go and u just take a picture and it will give u the answer
Answer:
c. a: 4
b: 12
c: 9
4x² +12x+9=0
(2x+3)(2x+3)= 0
(2x+3)²=0 {square root both sides}
2x+3=0
2x=-3
x= -3/2
P=648
