The length of a rectangle is 6 cm more
than the width. the area is 11 cm. find
the length and width.

The answer to your question is:  width = 1.47 and length = 7.47 m

Step-by-step explanation:

Data

length = width + 6 cm = x + 6

width = x

Area = 11 cm²

11 = (x + 6)x                       Substitution

11 = x² + 6x                         Simplify

x² + 6x = 11                         Factorise

x1 = 1.47             x2 = -7.47 length can not be negative

width = 1.47 cm

length = 1.47 + 6 = 7.47 m

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
