Answer:
∴(x+5)(x+3) =x²+8x+15
Step-by-step explanation:
Standard form of a polynomial:
Standard of polynomial means that the terms ordered from biggest exponent of variable to lowest exponent of variable.
Example:
Given,
(x+5)(x+3)
=x(x+3)+5(x+3)
=x²+3x+5x+15
=x²+8x+15
∴(x+5)(x+3) =x²+8x+15
The degree of the polynomial is 2 and is a one variable polynomial.
Answer:
Step-by-step explanation:
circumference = 2πr
2πr = 30π inches
Area = πr² = π*15*15 = 225π square inches
Answer:
Equations in slope-intercept form for three different lines that intersect at (–2, 3) are y=-x+1 , y=3 and y=x+5
Step-by-step explanation:
General equation of slope intercept form :
We are supposed to find equations in slope-intercept form for three different lines that intersect at (–2, 3).
Substitute the value in the general equation
y-3=m(x+2)
Now substitute any 3 values of m
At m = -1
At m =0
At m =1
They all intersect at the given point.
So, equations in slope-intercept form for three different lines that intersect at (–2, 3) are y=-x+1 , y=3 and y=x+5
