Did you mean :
f(x) = x² - 2x, find x = -3
f(-3) = (-3)² - 2(-3)
f(-3) = 9 + 6
f(-3) = 15
Answer:
322.24 meters
Step-by-step explanation:
The scale is 4 meter per centimeter. Multiply 5.3 by 4 to get 21.2 meters. Multiply 5.3 by 4 to get 15.2 meters. Multiply 21.2 by 15.2 to get 322.24
Answer:
1.5 or 3/2 teaspoons
Step-by-step explanation:
If her class has 36 students, and there are 12 cookies in every batch, then she needs 3 batches to give everyone in her class 1 cookie each. It takes 1/2 teaspoon for every recipe, so she needs 3 of those. 3 × 1/2 = 1.5 (or 3/2)
If you add 28 3/4 and 15 1/4 that is half way around The court that is 44m
So all the way around would be 44m×2= 88m
And he went around twice so 88m×2=176m
3x+4y = 375
6x+ 4y= 600
-------------------
6x-3x = 600 - 375
3x=225
x=225:3
x=75 cents
3*x+4y= 375
3*75+4y=375
225 +4y = 375
4y=375-225
4y=150
y=150:4
y=37,5 cents
the price is 75+37,5=112,5 cents for one bag of potato chips and one candy bar
