Answer:
m < -12
Step-by-step explanation:
Not sure if there's something missing in your equation.
-2(4+m) > 16
-2m-8>16
Add 8 to both sides to cancel out.
-2m - 8 [+8] > 16 [+8]
-2m > 24
Divide by -2 on both sides.
(-2m ÷ -2) > (24 ÷ -2)
m < -12
Answer:7.)A
8.)C
Step-by-step explanation:
Let x represent the width. Since the length is 3 more than 4 times the width, that would be equal to 3+4x. The perimeter is the sum of all sides, so that would be x+x+3+4x+3+4=86. Combine like terms, which would result in 10x+6=86. Subtract 6 from both sides giving you 10x=80. Divide by 10 giving you x=8. That means that the width is 8. The length is 3+4x. Substitute 8 for x giving you 3+4(8). Multiply, giving you 3+32, then add, which would give you 35. 35 is the length.
