Answer:
**********************868/14=62********************
Step-by-step explanation:
If the equation is given in factored form and the roots are real, then you can identify the x-coordinate of the vertex by averaging the 2 root values. For example, if the roots are -2 and 5, the x-coord. of the vertex is (-2+5)/2, or 3/2.
Once you have this x value, subst. the value into the given equation to calculate y. Then write the vertex as (x,y).
Where x is 4 the corresponding y is 5. Your answer is 5.
Answer:
17
Step-by-step explanation:
Assuming the field is a rectangle, the perimeter is found through the equation:

Since we know the perimeter and width, we can substitute and solve for the length.

Using the length and width, we can find the area.

The area is 2976 squared meters. We divide by the area a bag of canola seed can cover and round up if necessary to find the total number of bags.

Because we need a whole bag in order to cover for the decimal area, we round up to 17 bags.
Answer:
4x^2-x-4
Step-by-step explanation:
f(x) = 4x^2-3 and g(x) = x+1,
(f - g)(x)= 4x^2-3 -( x+1)
Distribute the minus sign
=4x^2-3 - x-1
Combine like terms
=4x^2-x-4
