Which lines are perpendicular to 2x−7y=−25? Select all that apply. a. y=2/7x -6
b. 7x+2y=−10
c. y−13=7/2(x+8)
d. 14x+4y=41

B and D

Step-by-step explanation:

slope = 2/7

perpendicular equals negative reciprocal

so slope must be -7/2

A = 2/7

B = -7/2

C = 7/2

D = -7/2

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
