The sketches below show cat's and fred's driveways. if the perimeter of each others of their driveways is the same, what is the length and width of cat's driveway?

40,12

Step-by-step explanation:

u count how many x's u have.4(for the first square)

add up the regular numbers

so u should have4x+50

repeat for the second one

so u should have 4x+25=6x+20

solve

u get 2x=30 simplify

u get 15

now plug it in and there is ur answer

its adding 5.5 each time

step-by-step explanation:

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
