What is the perimeter, in centimeters, of the rectangle who length is 60 centimeters and width is 20 centimeters?

P= 160cm

Step-by-step explanation:

length= 60cm

width= 20cm

160 cm.

Step-by-step explanation:

First you want to find the length which is 60 cm. then you want to multiply it by 2 because there are two sides that are 60 cm and you get 120. Next you find the width which is 20 cm. and multiply it by 2and you get 40.  Finally you add 120 cm. plus 40 cm. and you get 160 cm.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
