If you divided 18 objects into sets of 5, how many sets of 5 could you make? (you may draw a picture of objects or use real objects, like buttons or pennies, to you.) how many objects are left over?

18 divided by 5 is 3 with a remainder of 3. You have 3 sets of 5 with 3 objects left over.

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
