Answer:
(3,0), (4,0), (5,0)
on the x-axis at 3, 4 and 5
Step-by-step explanation:
This function is a lovely swoopey cubic curve. If we finish factoring it, it's not to hard to see the x-intercepts. You set it equal to zero and solve it. The solutions are the x-intercepts (are the "zeros")
0=(x-5)(x^2-7x+12)
0=(x-5)(x-3)(x-4)
0=x-5, 0=x-3 & 0=x-4
x=5, x=3, x=4
This is where the graph crosses the x-axis.
The sides of the rectangla are its length and width. We know the length is 5m longer than the width. Since we dont know the width, we can say that the width is x and the length is x+5.
The perimeter, as we know, is equal to the sum of all sides. We have two “length” sides and two “width” sides, so our equation is:
x + x + x+5 + x+5 = 46
Lets add all of this:
4x + 10 = 46
4x = 46-10
4x = 36
x = 36/4
x = 9
So our width is 9m and the length is 14m.
The area of a rectangle is width times length, so:
9*14=126m^2.
Answer:what are the answer choices
Step-by-step explanation:
3(1) - 8 = 3 - 8 = -5
just plug in 1 for x that's what f(1) means
