Answer:
infinite solution
Step-by-step explanation:
no matter what you have for x, 3x still equals 3x, so it is infinite
So basically you need to multiply 3000x4000 in two ways? If so you can use basic multiplication and an area model
Answer: 17.5 square yards
================================================
Work Shown:
base = 5 yards
height = 7 yards
The base and height are always perpendicular to one another
area of triangle = 0.5*(base)*(height)
area of triangle = 0.5*(5)*(7)
area of triangle = 17.5 square yards
The other values aren't used. They're likely thrown in as a distraction.
