Jennifer has a square bedroom. the area of her room is 144 ft2. what is the length of one side of jennifer’s room?
a 10 ft
b 12 ft
c 18 ft
d 36 ft

B.) 12 ft

Step-by-step explanation:

A square's sides are all the same: meaning, every side MUST be the same length. Then, all we have to do is find the square root of 144, which is 12.

To check this, we need to multiply the length times the height. If it equals 144, it is correct.

12 x 12 = 144

Hope I explained this well enough! If this seems confusing, or if you haven't learned square roots yet, you can always just try multiplying down the list of available choices to see what equals 144 c:

( 10 x 10 = 100, 12 x 12 = 144, 18 x 18 = 324, 36 x 36 = 936)

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?
