Cliff's math teacher, Ms. Madrigal, told him that the expressions 9 (2x + 6) - 43 and 14x + 54are equivalent. What would Cliff need to do first to 9 (2x + 6) – 4xto prove that Ms. Madrigal is correct.
A Subtract 4x from 2x
B. Add 2x and 6
C. Multiply 9 times 2x and
D. Add 4x to the - 4x and to the 2x

C.) Multiply 9 times 2x

Step-by-step explanation:

Usually, the first thing you want to do when simplifying an equation is to open the parenthesis. 9 multiplied by 2x, + 9 multiplied by 6.

step-by-step explan mxfcg'k; uafwgzfgjhklhgation:

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n

-75 degrees, 9 minutes and 35.3 seconds w
