Find the gcf. 12 and 45
a. 12
b. 180
c. 3
d. 45

GCF: 3

Step-by-step explanation:

We are asked to find GCF of 12 and 45.

We know that GCF stands for greatest common factor.

To find GCF of 12 and 45, we will write down factors of our both number and then find out the greatest factor that divides both numbers completely.

Factors of 12: 1, 2, 3, 4, 6, 12.

Factors of 45: 1, 3, 5, 9, 15, 45,

We can see that the greatest number that completely divides both numbers is 3, therefore, 3 is the GCF of 12 and 45.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
