You can use the discriminant rule, which is :
b^2 -4ac
“exactly one solution” means that it is equal to zero
so:
b^2 -4(4)(9)=0
b^2 -4(36)=0
b^2 -144=0
b^2=144
square root both sides
b=12 or -12

Answer:
24
Step-by-step explanation:
multiply 10 by 1.5 to get 15.
do the same with 16
The difference between the 2 times would be .055 seconds...
0.08.
0.8/10 is 0.08
the answer is 0.08
