Answer:
c
Step-by-step explanation:
it is non real if x²-36<0
x²<36
|x|<6
so -6<x<6
Answer:
A
Step-by-step explanation:
i think so..sorry if im wrong
P=2l+2w
Since it is given that P=26m, length is 5 more than its width (w+5), we'll work it out in the perimeter formula.
26=2(w+5)+2w
26=2w+10+2w
26=4w+10
4w=26-10
4w=16
w=4
Thus the width is 4m. Let's find the length.
l=w+5
l=4+5
l=9
The length of a pen is 9m.
