Rena wrote all integers 1 to 12. How many digits did she write

Rena wrote 15 digits

Rena wrote 15 digits.

Step-by-step explanation:

Starting with 10, you start adding 2 for every 2 digit number, so for 10, 11, and 12 you add 6 all together. 9+6= 15.

arithmetic sequence: a sequnce in which the diffrence between any two consecutive terms is the same

step-by-step explanation:

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 .
