C) or 2 is the solution to your question c:
Answer:
It has no perfect square factors, unless you count 1 = 1^2. That's sort of a degenerate case we don't usually count, since every integer has that factor. We would usually say that 1290 is a square-free integer. Hope this helps!!
Answer:
y=-4x+4
Step-by-step explanation:
equation of a line: y=mx+b (m:slope, b: y-intercept)
m=-4 (given)
y=-4x+b
substitute with (2, -4): -4=(-4)(2)+b
solve for b: -4=-8+b, b=4
y=-4x+4
Answer:
1:144
Step-by-step explanation:
if each floor is 15 feet, the whole building is 60 feet tall. so it does have a scale of 5 inches:60 feet but if you simplify that, its 1 inch: 12 feet, so you convert feet into inches by multiplying by twelve, which gives you a scale of 1:144 inches
