a + (n-1) b

= 3 + (7-1) 3

= 3 + 6(3)

= 3 + 18

= 21

Answer:

192

Step-by-step explanation:

given the geometric sequence : 3, 6, 12, ...

T1 = 3

r = 6/3 = 2

T7 =?

T7 = T1. r^(7-1)

= 3 . 2^(7-1)

= 3. 2^6

= 3. 64

= 192

hi <3

i'm not sure of which method you will have been taught but i'll try to explain the method i was shown.

so, you need to multiply the coefficient of x^2 by the last value

3 x -12 = -36

now, you need to find two values that multiply to make -36 but add to make 5.

9 and 4 would work. it would have to be positive 9 and negative 4, as these would subtract to give the 5 that you need

now we have:

(x - 4)(x + 9)

however, we need to achieve the 3 from somewhere so it needs to be divided somewhere

9 is divisible by 3 so you can divide it there. as 4 cannot divide by 3, you would move the 3 up to be the coefficient.

thus, your final answer would be:

(3x - 4)(x + 3)

hope this helps :)

Answer:

it's gonna be 3(X*2 + 4X - 4)

Step-by-step explanation:

Just factor out 3 from the expression

Step-by-step explanation: that is supposed to be subtraction i am 99.9% sure

Answer:

No, It is not equal to a 60% discount.

Step-by-step explanation:

Think of this. I go into a store and everything is 50% off and I have a coupon myself that is a 50% off discount for a specific item. It may seem like the item is now free, but it isn't. Imagine the item was $1 before any discount. Then the store took 50% off of the $1, leaving it at $0.50. So now with my discount of 50% off the item I will be taking this 50% off of $0.50 = my final discounted cost of $0.25.

Hope I helped you understand :)

Answer:

BD is congruent to BC. BD=BC

BD = 5x – 26, BC = 2x + 1, and AC = 43

To find out , we need to find  BC first . For that we have to find out x

WE know that BD=BC, using that we solve for x

Now we plug in 9 for x  and find out BC

BC=2x+1

BC=2(9)+1

BC=19

We know AC= 43

AC=AB +AC

43=AB+19

subtract 19

AB = 24

Answer:

(-2, 3)

Step-by-step explanation:

For x-4 you go left four places and y+6 go up 6 places

Answer:

(-2, 3)

Step-by-step explanation:

Point P has coordinates (2, -3).

The translation is (x - 4, y + 6) which means subtract 4 from the x-coordinate and add 6 to the y-coordinate.

The x-coordinate of point P is 2. Subtract 4 from it, you get -2.

The y-coordinate of point P is -3. Add 6 to it to get 3.

The coordinates of the translated point are (-2, 3).

Answer:

after 6 years

Step-by-step explanation:

thats when the lines intersect, (6,300)

There will be equal enrollment in Spanish and French classes after 6 years from now.

The red line shows the number of students enrolled in French class each year from now and blue line shows the number of students enrolled in Spanish class each year from now.

The point of intersection of the lines is the point which lies in both the line.

So, it represents the point or time when there are same number of students enrolled in both French and Spanish classes.

From the graph, we can see that the two lines at a point [tex](6,300)[/tex]. The value on the [tex]x[/tex]-coordinate shows the years from now. So, we can say that there will be equal number of students enrolled in two classes after 6 years.

Answer:

14810 votes

Step-by-step explanation:

The canidate won, so that means that they were the 7 instead of the 5.

Then you divide 20734 by 7, to see how many votes were for each "1". That's 2962.

Now you know that every "1" is worth 2962. Since the other candidate got 5, you multiply 5 by 2962 which is 14810.

The other candidate got 14810 votes.

Hope that made sense

Answer:

Answer:

AC = AB + BC

18 = (2X - 4) + (3X + 2)

18 = 5X - 2 ( add/subtract like terms)

20 = 5X (-2 take over otherside - 18 + 2)

X = 4

SUB X INTO AB AND BC

AB = 2(4) - 4 = 4

BC = 3(4) + 2 = 14

Answer:

Loss Amount: 175; Price: 3325

Step-by-step explanation:

You can multiply 3500 by 0.05 (which is 5% in decimal) to find how much is the loss. Then, you subtract the loss from the base price to find the new price.

Answer:

Loss =175, sold = 3325

Step-by-step explanation:

He bough at 3500

So 100 percent is 3500

And they said he had a 5% loss

So in other words, he sold it to Alex at 95% of the price he bought

So

3500 x 95%

3500 x 95/100

=3325

This is the price when Hitler sold it to alex

Now how much did Hitler lose?

3500 - 3325

=175

Step-by-step explanation:

295.6 divided by 10 is

29.56.

This can be easily done by moving the decimal up one place to the left. For 29.56 to the power of 2 is really just 29.56 * 29.56

29.56 * 29.56 is

873.7936.
