Since the legs are the same length, we know that the remaining two angles must be the same.
120+2x=180
2x=60
x=30
Final answer: x=30 degrees
I cant see your work very clearly so I'll work it out below:-
f(x + Δx) = (x + Δx)^2 - 2(x + Δx) - 3
= x^2 + 2x(Δx) + (Δx)^2 - 2x - 2(Δx) - 3
= x^2 - 2x + (Δx)^2 + 2x(Δx) - 2(Δx) - 3
144 ÷ 36 = 4
to solve a problem like this, flip it to a division problem
The answer would be 5.
You have to multiply the two variable which would be the amount of ice cream flavors and the number of toppings to get the amount which is 60. Since we don't know the number of toppings, we divide the whole amount (60) by the variable we do know (types of ice cream; 12) and we get 5.
