Sally, John & Mary had a discussion about Quadrilateral PQRS. Sally claimed that the figure represents an isosceles trapezoi

Kobotan [32]

Answer:

Step-by-step explanation:

Find the lenghth of the left and right sides using the distance formula to determine if the trapeziod is isosceles

$d=\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2}$

$PS=\sqrt{(2-1)^2+(0-4)^2}$

$PS=$ $\sqrt{17}$

$QR=\sqrt{(13-9)^{2}+(8-10)^{2}}$

$QR=$ $\sqrt{20}$

Since $PS\neq QR$ (the sides are not equal) this is not an isosceles trapezoid

Sally is incorrect and John is possibly correct.

Find the slope of the top and bottom sides to determine if this is a trapezoid.

$m=$ $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

SR: $m=$ $\frac{0-8}{2-13}$

$m=\frac{8}{11}$

PQ: $m=\frac{4-10}{1-9}$

$m=\frac{6}{8}=\frac{3}{4}$

since $mSR\neq mPQ$ (the slopes are not equal) the top and bottom sides are not parallel therefore this is not a trapezoid. Hence, John is incorrect, and Mary is ultimately correct.

Can you help me with this one

Vsevolod [243]

Answer:

For number 2 It would be 10x+12=29

For number 3 Try -37 Because i'm ending up with -36

Step-by-step explanation:

If the 2 was outside of the parenthesis you would multiply both numbers in the parenthesis
