P=2(l+w)

A= wl

80 factorization: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.

you then would have to find 2 numbers that would add up to make 42.

When you try 16*2+5*2= 32+10= 42 cm as your perimeter.

16*5= 80 cm^2 as your area.

melomori [17]

Answer:

Chantal and Trisha will have both traveled 105 miles in 20 minutes.

Step-by-step explanation:

$y$ is distance in miles, $x$ is time in hours.

The two equations are:

$y = \frac{20}{x} + 45$

$y = \frac{35}{x}$

Set them equal to each other and solve for x:

$\frac{35}{x} = \frac{20}{x} + 45$

$\frac{35}{x} - \frac{20}{x} = 45$

$\frac{35-20}{x} = 45$

$\frac{15}{x} = 45$

$x = \frac{15}{45} = \frac{1}{3} hours = 20 minutes$

Plug that back into the equations to confirm this $x$ gives the same $y$ :

$y = \frac{20}{1/3} + 45 = 105 miles$

$y = \frac{35}{1/3} = 105 miles$
