for a triangle to be similar, they have to have the same angle measures
Answer:
C. 3x^2 + 2x + 1
Step-by-step explanation:
A. 12^2 - (4*3*12) = 0 (there's one solution.)
B. (-3)^2 - (4*3*-18) = 255 (there're 2 real solutions.)
D. 3^2 - (4*0*-3) = 9 (there're 2 real solutions.)
C. 2^2 - (4*3*1) = -18 ✅✅
if b^2 - 4ac = negative then we can say that there isn't any real solution for the equation.
Answer:
the answer is 22.51 dollars.
Step-by-step explanation:
Answer:
a) His average speed is $48.53 miles/hour
b) His gas mileage is 21.71 miles per hour.
c) 1 gallon of gas is 1 gallon of gas = $3.29.
Step-by-step explanation:
A) Pira drives to California in 17 hours = 825 miles
Pira drives to California in 1 hours = (825/17) miles
= 48.53 miles/hour.
Therefore, his average speed is $48.53 miles.
B) Pira uses 38 gallons to drive 825 miles
Pira uses 1 gallon to drive 825/38 miles-per-hour
= 21.71 miles-per-hour
Therefore, his gas mileage is 21.71 miles per hour.
C) 38 gallons of gas cost = $125
1 gallon of gas = $125/38
1 gallon of gas = $3.29.
I think A becaus eits more thand the amount that they give you
