Answer:
3(2x+13) or 99
Step-by-step explanation:
Factor 6x+39
6x+39
=3(2x+13)/ 99
Answer:
3(2x+13) or 99
Since x represents the length (in meters), the width, which is 7 meters greater, is x +7. The product of these dimensions is the area (in square meters):
x(x +7) = 170
In standard form, the quadratic is ...
x² +7x -170 = 0
F(7) means f(x) when x = 7. The x is replaced with 7.
So we'll replace every x with 7 to go from x = 7 to 3-x = 3-7 = -4
Put another way
f(x) = 3-x
f(7) = 3-7
f(7) = -4
Answer: -4
