The product of 9 and the sum of three times a number and 8 is 180. what is the number? a) 4 b) 6 c) 12 eliminate d) 18

A

Step-by-step explanation:

Remark

Remember to read this over a little at a time.

9 *( 3*x + 8) = 180                     Remove the brackets

27x + 72 = 180                          Subtract 72 from both sides.

27x = 180 - 72                           Combine

27x = 108                                   Divide by 27

x = 108/27

x = 4                                          Answer

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

answer4 to the second power is 16

and 4 to the third power is 64,
