Final answer:
By applying the concept of multiplication, we determine that Marcus walks his dog a total of 3.6 miles in 6 days if he walks 3/5 of a mile each day.
Explanation:
This question actually involves simple mathematics, specifically the concept of multiplication. Since Marcus walks his dog 3/5 of a mile each day, in order to calculate how far Marcus walks his dog in 6 days, we simply multiply the daily distance by the number of days. Therefore, the calculation will be as follows: 3/5 mile/day * 6 days = 18/5 miles = 3.6 miles.
So, Marcus walks his dog a total of 3.6 miles in 6 days.

First part: when (6x + 2) is positive
6x + 2 < 10
6x < 10 - 2
6x < 8
x < 8/6
x < 4/3
Second part: when (6x + 2) is negative.
-(6x + 2) < 10 Divide both sides of inequality by -1 and change the sign.
(6x + 2) > -10
6x + 2 > -10
6x > -10 - 2
6x > -12 Divide both sides by 6.
x > -12/6
x > -2.
Combined solution: x < 4/3 and x > -2
-2 < x < 4/3.
Graph is a line on the number line between -2 and 4/3.
-2 and 4/3 are excluded from solution.

Answer:
x = 8, perimeter of triangle = 22 units
Step-by-step explanation:
the perimeter is the sum of the sides of the triangle , that is
x + x + 2 + x - 4 ( collect like terms)
= 3x - 2
the perimeter of a rectangle is calculated as
2 ( length + breadth )
= 2(x + 3) ← distribute parenthesis by 2
= 2x + 6
equate the 2 expressions for perimeter
3x - 2 = 2x + 6 ( subtract 2x from both sides )
3x - 2x - 2 = 2x - 2x + 6 ( simplify both sides )
x - 2 = 6 ( add 2 to both sides )
x - 2 + 2 = 6 + 2 ( simplify both sides )
x = 8
The perimeter of triangle is then
= 3x - 2
= 3(8) - 2
24 - 2
= 22 units
