Jrs124 is redesigning the classrooms. each classroom will have a length that is 8 feet more than the width. the perimeter will be 136 feet. create and use an algebraic equation to find the dimensions (length and width), in feet, of the new classroom. show your work.

Suppose a man is heterozygous for heterochromia, an autosomal dominant disorder which causes two different‑colored eyes in an individual, produced 25‑offspring with his normal‑eyed wife. of their children, 15 were heterochromatic and 10 were‑normal. calculate the chi‑square value for this observation.

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.
