Answer:
-35
Step-by-step explanation:
-5 (x + 2) + 5 (x -5)
Expand:
= -5x - 10 + 5 (x - 5)
Expand once more:
= -5x - 10 + 5x - 25
Simplify:
-35
Given that the function is given by:
f(x)=2x+x
when x=3, then:
f(3)=2(3)+3
f(3)=6+3
f(3)=9
b] The zero of the function will be given by:
f(x)=2x+x=3x
When x=0 then f(x)=0, hence the zero of the function will be at x=0
The answer is 4x^3+12x^2-5x-1
The question doesn't say how many sides you have,
so the answer will have to be something that applies to
ALL polygons, no matter how many sides they have.
A polygon in which all sides are the same length and
all angles are the same size is called a "regular" one.
If a polygon with 4 sides is regular, we call it a "square".
