These are the statements I think is true:

The parallelogram and rectangle formulas are both the same.

In the trapezoid formula, the bases are added.

Explanation:
I’ll just give you the formulas..

Area for trapezoid:
(a + b) ÷ 2 x h
a & b are the bases, h is for height.

Area for rectangle:
Length x width

Area for parallelogram:
Base x height
(Choose the height that is perpendicular to the base)

Also, I would liek you to know I did not understand the other few choices because ai think they have wrong grammar. But I really tried my best for now.

HOPE THIS HELPS!

A circle has its center at the origin, and (5, -12) is a point on the circle. How long is the radius of the circle?

Amanda [17]

Option C

The radius of circle is 13 units

Solution:

The equation of circle is given by formula:

$(x-h)^2+(y-k)^2 = r^2$

Where, the center being at the point (h, k) and the radius being "r"

Given that circle has its center at the origin

(h, k) = (0, 0)

(5, -12) is a point on the circle

(x, y) = (5, 12)

Substituting in equation we get,

$(5-0)^2+(12-0)^2 = r^2\\\\5^2+12^2 = r^2\\\\r^2 = 5^2+12^2\\\\r^2 = 25 + 144\\\\r^2 = 169\\\\Taking\ square\ root\ on\ both\ sides\\\\r = \sqrt{169}\\\\r = \pm 13\\\\Since\ radius\ cannot\ be\ negative\ ignore\ r = -13\\\\Thus\ the\ solution\ is:\\\\ \r = 13$

Thus radius of circle is 13 units

14x = -22 - 5y 5x = 60 + 5y Enta

Kazeer [188]

Answer:

x=2 y=-10

Step-by-step explanation:

14x =-22-5y eq---1

5x= 6 =5y eq --- 2

Subtract eq 1 from eq 2 we get the value of x

x= 2

put x = 2 in equation 1

14 x = -22 - 5y

14 (2) = -22 - 5y

28 =-22 - 5y

+22 =-5y

50 = -5y

y= - 50/5

y = - 10
