Answer:
x = 10
Step-by-step explanation:
22 - 2x + 4(x - 2) = 34
22 - 2x + 4x - 8 = 34
22 - 8 - 2x + 4x = 34
14 + 2x = 34
-14 -14
--------------------------------
2x = 20
/2 /2
--------------------------------
x = 10
5+7+11=23
3+11+53=67
3+11+61=71
are some examples
Volume = 5 cm * 10 cm * 2 cm
volume = 100 cm³
massa = 700 g
Densidade = massa / volume
D = 700/100
D = 7 g / cm³
First simplify the square root of 1/25
-√1/25
Rewrite using the quote by rule for radicals.
-√1/√25
Any root of 1 is 1
-1/√25
Simplify the denominator. (find the square root of 25)
-1/5
The result can be shown in both exact and decimal forms.
Exact form: -1/5
Decimal form: -0.2
Answer:
Step-by-step explanation:
By definition a diameter goes through the center of the circle. So if we find the midpoint of the diameter, we will have the h and k of the center. Then we will use one of the points ON the circle as x and y and solve for r. Here goes:
to get a midpoint/center of (0, -9).
The standard form of a circle is
Filling in with h, k, x, and y:
which simplifies to
so
Now we can write the equation of the circle:
