Step-by-step explanation:
we know that
The area of the rectangle ( a dining room table) is equal to

where



substitute

Apply difference of squares right side


Remember that the length cannot be a negative number
so
x=2
<em>Find the length</em>

<em>Find the width </em>

Answer:
13. 7=108 degrees
14. 8=70 degrees
15. 8=38 degrees
16. 6=73 degrees
17. 6=80 degrees
Step-by-step explanation:
13. If 6=72 what is 7
Angles on a straight line add to 180
180-72=108 degrees
14. If 9 = 110 what of 8
Angles on a straight line add to 180
180-110=70 degrees
15. If 7 =142 what of 8
Angles on a straight line add to 180
180-142=38 degrees
16. If 9 =107 what of 6
Angles on a straight line add to 180
180-107=73 degrees
17. If 8=80 what of 6
Direct opposite Angel's are equal so 6 =80 degrees
Hello :
W(a) = a/15
W(60) = 60/15 =4...(Answer : D )
You can re-write this quotient this way :

What's inside the square root must be greater than or equal to 0, because the domain of the square root function is defined on R+ (which is [0,+∞))
In other word we must find x so that :

at the end we get
28(x-1) ≥ 0
28x - 28 ≥ 0
28x ≥ 28
x ≥ 1
So the answer is B, x ≥ 1
