Answer:

The distance is √ 85 units

Step-by-step explanation:

To find the exact value, all we will simply do is to use the distance formula to solve;

D =√ (x₂ - x₁)² + (y₂ - y₁)²

From the question given;

The points given are (−1, 4) and (6, −2)

so; x₁ = -1 y₁ = 4 x₂ = 6 y₂ = -2

We can now proceed to substitute the formula into the equation

D = √ (x₂ - x₁)² + (y₂ - y₁)²

=√ (6 - -1)² + (-2 - 4)²

=√ (6+ 1)² + (-2 - 4)²

=√ (7)² + (-6)²

=√ 49 + 36

=√ 85

The distance is √ 85 units

90units needed 8 units per case what's the #of cases & # of additional units

Kobotan [32]

Answer:

# of cases: 11

Additional units: 2

Step-by-step explanation:

If each case can hold 8 units, and we want to find the total # number of cases, we have to divide the # of units (8) for one case by the total # units (90).

As you can see, after dividing by 8, we have a total of 11 cases and a remainder of 2 units. The remainder will be the # of additional units because we cannot have another case filled with 8 units.
