Answer:
8
Step-by-step explanation:
If the only zero for this function is at x = - 4 it looks like this:
f(x) = (x+4)(x+4) = x^2 +8x + 16 <u> so j = 8 </u>
Answer:
w=4
Step-by-step explanation:
adding a negative is like subtracting so w=11-7
First find the circumference of the circle.
Circumference:

Plug in 20 for the radius (r).

= 125.66
The circumference of the circle is 125.66 cm.
Now to find this in meters... there are 100 centimeters in 1 meter.
Divide 125.66 by 100 to find how many meters this is.
125.66 ÷ 100 = 1.26
The circle's circumference is 1.26 meters.
Answer: It would be 7x + 4
