Which equation represents the line that passes through the points (-3, 7) and (9, -1)?
O y=-3x+5
O y=-x-7
o y = 2 x - 7
o y = 2 x + 5

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

: )

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

perimeter of the base times height
