(3,-1)
It needs to be written in standard form before you try to solve it.
For the answer to the question above, <span>if
a1 = 2,
then
a2 = 3a1 + 1
a3 = 3a2 + 1 = 3
Then, we can finally solve for terms of sequence.
(3a1 + 1) + 1 = 9a1 + 4 = 9(2) + 4 = 22
So the answer to your question is,
</span><span>22, 67, 202, 607

I hope my answer helped you. Have a nice day!
Answer:
Step-by-step explanation:
1) If you really meant X^2+12=40, then this simplifies to x^2 = 28, and therefore x = ±√28, or x = ±2√7.
2) If you meant X^2+12x=40:
a) Take half of the coefficient of x: that would be (1/2)(12), or 6.
b) Square this result, obtaining: 6² = 36
c) Add this 36 to x^2 + 12x + 40, and then subtract it: We get:
x² + 12x + 36 - 36 = 40, or x² + 12x + 36 = 76
We have to add 36, as indicated above, to "complete the square."
Answer:
The area of each figure is:
- <u>Area of the rectangle = 10 square units.</u>
- <u>Area of the triangle = 10 square units.</u>
- <u>Area of the figure = 20 square units.</u>
Step-by-step explanation:
To find the area of that figure, first, we're gonna find the area of the rectangle and next the area of the triangle, to make this we need to identify the measurement of each one, the rectangle has 2 units wide and 5 units high, then, we use the next formula:
- Area of a rectangle = width * height
- Area of a rectangle = 2 units * 5 units
- <u>Area of a rectangle = 10 square units</u>
Now, we identify the measurements of the triangle (base = 4 units, height = 5 units) and we use the formula:
- Area of a triangle = (base * height) / 2
- Area of a triangle = (4 units * 5 units) / 2
- Area of a triangle = (20 square units / 2
- <u>Area of a triangle = 10 square units</u>
And we obtain the area of the whole figure when we add the two areas:
- Area of the figure = area of the triangle + area of the rectangle
- Area of the figure = 10 square units + 10 square units
- <u>Area of the figure = 20 square units</u>.
As you can see, <u><em>the area of the picture is 20 square units</em></u>.
Answer:
Step-by-step explanation:
In order to convert kilometers to miles, we can use a formula, assuming 
is miles and 
is kilometers.
.
Since we know the kilometer reading (7), we can divide this by 1.609 to get our total miles.
Hope this helped!
