Henry cuts two of his neighbor's lawns. The first is 7 ft long and 3 ft wide. What is the area? The second lawn takes Henry 4 times as long to cut and he knows that all the lawns have the same length dimension. What is the width of the second neighbor's lawn?

it would be 6xy and -16xy.

40 minutes

step-by-step explanation:

add the time and multiply by 2

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
