Answer:
C. 12 (2m - p + 6)
Step-by-step explanation:
just distribute
12 (2m) = 12m
12 (- p) = -12p
12 (6) = 72
2|7 − 7x| = 2x + 4
|7 - 7x| = x + 2
7 - 7x = x + 2 or 7 - 7x = -(x + 2)
-8x = -5 or 7 - 7x = -x - 2
x = 5/8 or -6x = -9
x = 5/8 or x = 9/6
x = 5/8 or x = 3/2
To check for extraneous solutions, we check both solutions in the original equation.
<em>Check solution 5/8:</em>
2|7 - 7x| = 2x + 4
|7 - 7x| = x + 2
|7 - 7 * 5/8| = 5/8 + 2
|56/8 - 35/8| = 5/8 + 16/8
21/8 = 21/8
<u>Solution x = 5/8 works.</u>
<em>Check solution 3/2:</em>
2|7 - 7x| = 2x + 4
|7 - 7x| = x + 2
|7 - 7 * 3/2| = 3/2 + 2
|14/2 - 21/2| = 3/2 + 4/2
|-7/2| = 7/2
7/2 = 7/2
<u>Solution 3/2 also works.</u>
Answer: x = 5/8 or x = 3/2

Answer:
a. 22.5953 b. 3.6
Step-by-step explanation:
A. When a number is in parentheses and directly beside another number it means multiple. so you simply multiply to two together.
B. When a number is in parentheses but has a division sign or forward slash in front of it it is simply keeping the number separate as not to create confusion so just divide them.
ps. when you teacher says shoe work he/she means dint just write an answer. They mean write out beside your answer "2.43 x 9.71 = 22.5953" & "4.68 ÷ 1.3 = 3.6"
