Which statement about quadrilateral WXYZ can be proved to be true?

a. Diagonals of WXYZ are congruent.

b. Consecutive angles of WXYZ are supplementary.

c. The diagonals of WXYZ bisect opposite angles.

d. Consecutive angles of a parallelogram are congruent.

A. Diagonals of WXYZ are congruent

Step-by-step explanation:

If the quadrilateral is a rectangle, the diagonals of a rectangle are congruent

Similarly an isosceles trapezoid is a quadrilateral that must have congruent diagonals. A square, because it is a rectangle, is a quadrilateral that must congruent diagonals. But it is possible to have a quadrilateral with no additional properties that may have congruent diagonals.

The Answer is C

Step-by-step explanation:

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

where are the images of the functions i can only see the question you typed.
