Answer:
The zeros are x1=4.45 and x2=-0.45.
x1 is between 4 and 5.
x2 is between -1 and 0.
Step-by-step explanation:
We have the function:
As this is a quadratic function, we can calculate the zeros of the function with the quadratic equation:
The zeros are x1=4.45 and x2=-0.45.
x1 is between 4 and 5.
x2 is between -1 and 0.
Answer:
perimeter = 2(x + 5)
this is 2x + 10
x = 55 inches
Step-by-step explanation:
this question is a bit weird because they didn't put the units for 5, so I'm assuming it's in inches...
the perimeter of a rectangle will have two of each, so we can put the 2 outside the bracket since it applies to everything. We have x and we have 5 so put those in the bracket with a plus sign because you add when you're calculating the perimeter.
5 + 5 = 10
120 - 10 = 110 inches (this is 2x)
110 ÷ 2 = 55 inches
The two towns would be 60 miles apart. Because 2 inches divided by 0.5 inches is 4. So you have to multiply 15 miles and you’ll 60 miles
