8.4 x 10^12 / 4.2 x 10^6 = 2 x 10^6
Answer: a = -5
Step-by-step explanation:
2(a+3)=-4
Distribute
2a+6=-4
subtract the six with the four and you get -10
-6-4=-10
now divide 2a with -10
you get a= -5
you can plug the answer in
Answer:
268.0 in²
Step-by-step explanation:
refer to attached graphic as reference
volume of cone, V = (1/3) πr²h
in our case, we are given r = 4" and h = 16"
substituting this into equation:
V = (1/3) πr²h
= (1/3) ·(3.14) · (4)²· (16)
= 267.94667 in²
= 268.0 in² (nearest tenth)
It's 1 haha. one squared is one and add and you get 2
The value of <em>x </em>in the equation, (3x + 30), is 10.
