Answer:0=12

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:

3x-7=3x-5

Combine like terms:

3x-3x=7+5

0=12

Following one side of a rural road, the house numbers increase by eighteen. The house number of the first house on the road is 8
ad-work [718]

Answer:

<u>Recursive:</u>

a_n=a_{(n-1)}+18\\ \\ a_1=82

<u>Explicit:</u>

a_n=64+18n

Explanation:

<u>1. Sequence:</u>

a_1=82\\ \\ a_2=82+18=100\\ \\ a_3=100+18=118\\ \\ a_4=118+18=136\\ \\ ...

<u>2. Recursive formula</u>

The recursive formula permits to calculate the value of the nth term in the sequence using the (n-1)th term in the sequence.

a_n=a_{(n-1)}+18\\ \\ a_1=82

<u>3. Explicit formula</u>

The explicit formula permits to calculate any value of a term in the sequence:

a_n=a_1+(n-1)d\\ \\ a_n=82+(n-1)18\\ \\ a_n=82+18n-18\\ \\ a_n=64+18n

A circle has An area of 36 pi square inches which best represents the circumference of the circle.
kkurt [141]

Answer: 12πins.

Step-by-step explanation:

Since the area if a circle = πr²

From the question

Area of the circle = 36πins²

To find the circumference of the circle, we need to find the common radius of the circle and this could be achieved from the area of the circle given above.

πr² = 36π, solving this gives. Divide through by π

r² = 36

r = +/-√36

= +/-6

Now to find the circumference of the circle, we substitute for r in the formula below.

Circumstances = 2πr

= 2 ×π × 6

= 12πins.

I need help with math
Nata [24]

Answer:

Question 13. I believe is C.

Step-by-step explanation:

take your area of the face you are given aka your 7 5/6 and multiply it by six since there are six faces.

You can convert the mixed number to an improper fraction

     7 \frac{5}{6}  = denominator times the whole number ( 6x7)= then add the numerator    (42+5)=\frac{47}{6}

Then multiply by six to get your answer

I'm not completely sure about question number fourteen so I am not answering it.

goldenfox [79]

Answer:

Step-by-step explanation:

6k^3+10k^2-56k\\2k(3k^2+5k-28)\\=2k[3k^2+12k-7k-28]\\=2k[3k(k+4)-7(k+4)]\\=2k(k+4)(3k-7)

common factor is 3k-7

Ok think about it 1/4 plus 1/2 is 3/4

so how do i go to negitives?

you double the amount of it and then minus it

because 3/4- 3/4 would be zero

so you have to double it to get that answer

have a wonderful day filled with only joy!
