(n+5)^2=48
sqrt both sides
n+4=+/-4√3
minus 4 both sides
n=-4+/-4√3
-4+4√3>0 so this cannot be the value of n
n=-4-4√3
the number is -4-4√3
Answer:
V = 3216.9 
Step-by-step explanation:
Volume of a cylinder = π 
h
We are given diameter, 16cm, and half of it is the radius
r = 8cm
h = 19cm
Substitute the values into the equation
V = π * 
* 19
V = 3216.9
1.5(x + 4) - 3 = 3.5(x - 2)
We need to use the distributive property to simplify this.
1.5x + 6 - 3 = 3.5x - 7
<em><u>Subtract 1.5x from both sides</u></em>
6 - 3 = 2x - 7
<em><u>Simplify left side</u></em>
3 = 2x - 7
<em><u>Add 7 to both sides</u></em>
10 = 2x
<em><u>Divide both sides by 2</u></em>
x = 5
Answer:
5/7
Step-by-step explanation:
You find a slope by using the equation y2-y1/x2-x1.
In this case: 15-5/21-7
10/14
5/7
