4x - 1 < 11
Add 1 to both sides
4x < 12
Divide both sides by 4
x < 3
x is less than 3
At least 15 b/c is you add QWERTY to -12, you get zero and adding 5 to get 15 in total.
D because the shaded region has one side and subtract by pie and substitute to get this answer.
I don’t know what your asking
Let distance be s and velocity be v
s = 5t⁴ - 10t² + 6
We know velocity is the change in distance per unit time, so
v = ds/dt
v = 20t³ - 20t
