the area of a rectangle is given by the expression x² +5x-6,is 98sq meters. find the dimension of the rectangle
Answer (1)
Answer:The width is 8 and length is 12.25Step-by-step explanation:x²+5x-6=98put all the numbers on the left sidex²+5x-104=0after this you can factor using quadratic formula or general trimonialin this solution I will use the general trimonialwhat two numbers will add on to 5 and will multiply into 108?-8 and 13so (x-8) (x+13)x=8 or x=-13i will use the 8 because -13 is impossible in this scenarioso one side of the equation is down98=8×x98÷8=x12.25=xso those qre the dimensions
