Answer:
width=4in.
length=13in
Step-by-step explanation:
let the width of the rectangle be x
then the length will be x+9
Area= length×width
52= (x+9)x
52= x²+9x
x²+9x-52=0
x²+13x-4x-52=0
x(x+13) - 4(x+13)= 0
(x-4)(x+13)=0
x=4 or -13
dimension cannot be negative
hence x=4in
the width is 4in. and the length is 4+9=13in.
Cookies = 24
drinks = 8
Apply ratios
Cookies / drinks = 24/8 = 3
drinks /cookies = 8/24 = 1/3
5.
There are 3 times as many cookies as drinks
There are 1/3 times as many drinks as cookies
6.
drinks = 8
pizzas = 2
Drinks/pizzas = 8/2 = 4
Pizzas / drinks = 2/8 = 1/4
There are 4 times as many drinks as pizzas.
There are 1/4 times as many pizzas as drinks.
7.
Cookies = 24
pizzas = 2
Cookies /pizzas = 24/2 = 12
Pizzas / cookies = 2/24 = 1/12
There are 12 times as many cookies as pizzas.
There are 1/12 times as many pizzas as cookies.
