(! ) william completed the following order of operations problem recently on a test. 10 – 4 ÷ (2) + (9 – 5) ● 3 he worked the problem from left to right and got an answer of 21. his teacher marked the problem incorrect. why is william’s answer incorrect? show and explain what william did incorrectly. then, solve the problem correctly and explain how you got the correct answer.

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 .
