(3a) |-12|< |15| bc the absolute value of -12 is 12. 15 is greater than 12.
(3b) -3/4 is less than -2/3. We can find this by converting the fractions into decimals. -3/4 = -.75 -2/3 = -.66
2 yards. 2 inches is 2 yards because 1 yard is 36 inches
Answer:
g(n) = 2n^2 - 4n; Find g(-9)
The answer is 170, because you have to plug in -9 for all the N values. When you do that, just follow PEMDAS.
P-Parentheses
E-Exponents
M-Multiplication
D-Division
A-Addition
S-Subtraction
Step-by-step explanation:
g(-9) = 2(-9)^2 - 4(-9)
g(-9) = 18^2 -4(-9)
g(-9) = 134+36
g(-9) = 170
I really hope this helps!

Step-by-step explanation:
congruent is define as the same shape and size. AAA only prove the two triangle iare same shape but not same size.
Since the first car travels 55 miles per hour and starts an hour early, by 4:00 it is 55 miles away from the other car. Therefore, the equation is 55+a(some value)+b(another value)=380. If a car travels 55 miles per hour, that means that we add 55 for each hour and 55*x (if x is the number of hours) is the distance traveled. We have accounted for the first hour, so this is similar to saying that they start 55 miles away at 4:00 and go from there. For the other car, since it travels 75 miles per hour, its distance in hours is 75*x (the amount of time spent should be the same if we start at 4:00). Therefore, since they travel away from each other, our total distance is 55+55x+75x=380. Subtracting 55 from both sides (and combining like terms), we get 130x=325. Next, we divide both sides by 130 to get 2.5 hours, or 2 hours and 30 minutes
