Naomi and Hudson work at a dry cleaners ironing shirts. Naomi can iron 35
shirts per hour, and Hudson can iron 20 shirts per hour. Naomi and Hudson
worked a combined 13 hours and ironed 395 shirts. Write a system of
equations that could be used to determine the number of hours Naomi
worked and the number of hours Hudson worked. Define the variables that
you use to write the system.

ok so what's the question?

step-by-step explanation:

using pemdas, (order of operations) you'll see the answer is 24.

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
