Arectangle's length and width are in a ratio of 5: 2. the area is 160 square centimeters. what are the length and width?
if you could solve this do so asap

Step-by-step explanation:

l - length

w - width

length and width are in a ratio of 5:2

          cross multiply

         divide both sides by 2

the area is 160cm²

We have the system of equations:

Substitute (1) to (2):

Put the value of w to (1):

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

answer:

1.14285714286

step-by-step explanation:

divide 40 into 35 and you will get your answer
