Answer:
I think of having straight line
For zeroes/roots r1,r2, r3
the facors of the polynomial is
(x-r1)(x-r2)(x-r3)
roots
-3,2,5
(x-(-3))(x-2)(x-5)
(x+3)(x-2)(x-5)
the coefient of the x term is -4
so mutliply the whole thing by 2
(2)(x+3)(x-2)(x-5)
expand
f(x)=2x^3-8x^2-22x+60
9 inches across the floor Brendan rolls his ball if Sydney rolls a ball 63 inches across the floor.
<h3>What is linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
Sydney rolls a ball 63 inches across the floor. This is 7 times the distance that Brendan rolls his ball across the floor.
Sydney rolls = 7n
Here n represent the number of inches Brendan rolls his ball.
63 = 7n
n = 63/7 = 9 inches
Thus, 9 inches across the floor Brendan rolls his ball if Sydney rolls a ball 63 inches across the floor.

Answer:
14.13
Step-by-step explanation:
it is between 14 and 15, the sum is equal to 9, 3 is in the hundreds place
(x + 2y) ^2
(x + 2y) (x + 2y)
x^2 + 2xy + 2xy + 4y^2
= x^2 + 4xy + 4y^2
