The trapezoids are similar, find

X = 7

Step-by-step explanation:

7 + 1 = 8

7 - 3 = 4

4 is half of 8

x = 7

Step-by-step explanation:

To find the value of x we can use similarity ratio

3/6 = (x-3)/(x+1) cross multiply expressions

3x + 3 = 6x - 18

3 + 18 = 6x - 3x

21 = 3x divide both sides by 3

7 = x

is there a picture

step-by-step explanation:

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?
