Answer:
The width would be 9 + x
Step-by-step explanation:
In order to find this, we must first factor the area. This will give us two things that are being multiplied together.
81 - x^2 = (9 - x)(9 + x)
Since the area is the length times the width and the width is x - 9, we know the length must be x + 9
Because it is normally set to only find real roots, not complex roots
if you are smart, you can use the factor function and use your head to find those roots
Step-by-step explanation:
a. lim(x→2) [g(x) + h(x)]
Use additive property of limits.
= lim(x→2) g(x) + lim(x→2) h(x)
= 0 + 5
= 5
b. lim(x→2) [3 h(x)]
Use multiplication property of limits.
= [lim(x→2) 3] [lim(x→2) h(x)]
= 3 lim(x→2) h(x)
= 3 (5)
= 15
c. lim(x→2) [g(x) h(x)]
Use multiplication property of limits.
= [lim(x→2) g(x)] [lim(x→2) h(x)]
= (0) (5)
= 0
Hey there!!
Given :-
... c² - 4c = 0
... c ( c - 4 ) = 0
... c - 4 = 0
... c = 4
<em>The value of c is '4'. </em>
Hope my answer helps!!

Explanation:
Make use of the properties of equality.
a = 2b +6 . . . . . given
a = 9b -8 . . . . . given
2b +6 = 9b -8 . . . . . . . substitution property of equality
6 = 7b -8 . . . . . . . . . . . subtraction property of equality
14 = 7b . . . . . . . . . . . . . addition property of equality
2 = b . . . . . . . . . . . . . . . division property of equality
b = 2 . . . . . . . . . . . . . . symmetric property of equality
