The area of a rectangular hot tub is (8x-2) square units. What are possible dimensions of the hot tub cover?

{1 unit by (8x - 2) units}, or {2 units by (4x - 1) units}.

{(8x - 2) units by 1 unit}, or {(4x - 1) units by 2 units}.

Step-by-step explanation:

The area of the rectangular hot tub is (8x - 2) sq. units.

If the dimensions of the hot tub cover are all whole numbers, then the possible dimensions of the hot tub cover will be {1 unit by (8x - 2) units}, or {2 units by (4x - 1) units}.

On the other way, the dimensions may be {(8x - 2) units by 1 unit}, or {(4x - 1) units by 2 units}. (Answer)

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
