The greatest common factor is 12 because 12 times 3 is 36 and 12 times 7 is 84.

Hope this helps! :)

To get the GCF of 36 and 84 we need to factor each value first and then we have to choose all the copies of factors and multiply them:

36: 2233
84: 223 7
_________
GCF = 223

The Greates Common Factor (GCF) is: 2 x 2 x 3 = 12

Answer: 12

Hope this helps you! :)

elena55 [62]

Answer:

please mark me brainliesf if it helps you

f(x) = -3x+1

or, y = -3x + 1

Interchanging the position of x and y, we get,

x = -3y +1

or, 3y = 1 - x

or, y = 1 - x /3

: . f^-1(x) = 1-x / 3

I NEED HELP ASAP

Alright, lets get started.

If the polygon measures 45 degree exterior angle and we are asked to find number of sides, there is a formula for that.

$\frac{360}{n}$ = value of exterior angle

Where n is number of sides of ploygon

$\frac{360}{n} = 45$

Multiplying n into both sides

$\frac{360}{n} * n = 45 n$

$360 = 45 n$

Now divide 45 in both sides

$\frac{360}{45} = \frac{45n}{n} = n = 8$

n = 8

Means number of sides of polygon is 8, hence its Octagon. Answer

Now we have given 45 exterior angle hence interior angle would be

180 - 45 = 135°

So, sum of all interior angles would be = number of sides * interior angle

sum of all interior angles would be = $8 * 135 = 1080$

Hence sum of all interior angles would be 1080°. Answer

Hope it will help :)

5/2c-3=3/7c+4 and please explain

Naddika [18.5K]

5/2c - 3 = 3/7c + 4...subtract 3/7c from both sides
5/2c - 3/7c - 3 = 4.....add 3 to both sides
5/2c - 3/7c = 4 + 3....common denominator of 7 and 2 is 14
35/14c - 6/14c = 7...simplify
29/14c = 7....multiply both sides by 14/29, eliminating the 29/14 on left
c = 7 * 14/29
c = 98/29 = 3 11/29

kherson [118]

So it would be in six years because if you do it, it would be
garden 1: 2,4,6,8
garden 2: 3,6,9
and the lowest common multiple is 6 so in 6 years is when it will happen again
