Answer:
x=9
Step-by-step explanation:
Zeros are
Write in factor form and solve
- (x-0)(x-(-3))(x-(-4))=0
- x(x+3)(x+4)=0
- x[x(x+4)+3(x+4)]=0
- x(x²+4x+3x+12)=0
- x(x²+7x+12)=0
- x³+7x²+12x=0
Points given (-2,16)
Solve for n
On solving we get
So the function is
- y=-4(x³+7x²+12x)
- y=-4x³-28x²-48x
Answer:
4.24 inches
Step-by-step explanation:
1 inch / 50 miles = x / 212 miles Cross multiply
1 inch * 212 miles = 50 miles * x Divide by 50 miles
1 inch * 212 miles / 50 miles = x
x = 4.24 inches.
How much is 0.24 of an inch?
0.24 * 50 = 12
So 0.24 inches represents 12 miles.
