Answer:
x = 28.
Step-by-step explanation:
1/2x - 12 = 12
Add 12 to both sides:
1/2x - 12 + 12 = 12 + 12
1/2x = 24
Now, to isolate x we multiply both sides by 2:
1.2 x * 2 = 24 * 2
x = 48.
The answer to this question is:
A circle is growing so that the radius is increasing at the rate of 2cm/min. How fast is the area of the circle changing at the instant the radius is 10cm? Include units in your answer.?
✔️I assume here the linear scale is changing at the rato of 5cm/min
✔️dR/dt=5(cm/min) (R - is the radius.... yrs, of the circle (not the side)
✔️The rate of area change would be d(pi*R^2)/dt=2pi*R*dR/dt.
✔️At the instant when R=20cm,this rate would be,
✔️2pi*20*5(cm^2/min)=200pi (cm^2/min) or, almost, 628 (cm^2/min)

Z is greater than or equal to 7.
you would put a 7 near the front of the number line and put a colored in circle above it. then you would draw a line from the circle to the other end of the line
Answer:
b. second answer.
Step-by-step explanation:
I think b.
I replaced the x in x-2 with 2, and the x in x+3 with -3, and got zero on both. 0x0=0
2/0=undefined
