PLEASE HELPP WILL MARK BRAINLIEST! ABCD is a rectangle. If AC=x+12 and BD=4x−3, find the value of x. Round to the nearest whole number if necessary.

Find the length of EC. Round to the nearest tenth if necessary.

EC =

The answer would be d i think but i’m for sure it is not a and c

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.

M< 5 = 80 , < 2 = 80, < 6= 100, < 3= 100, < 7= 80, < 4= 80, < 8= 100
