Answer:
the answer is G) Change 30 to 3,000
The answer is 0 < x <span>≤ 7
</span>
First, we know that width = x
Which means that length = x +18
So, the possible equation for the Table's area is
X (X + 18) ≤ 175
X^2 + 18x - 175 <span>≤ </span>0
Next, we need to calculate is by using complete square method
x^2 + 18x + 81 <span>≤ 175 + 81
(x + 9)^2 </span><span>≤ 256
|x + 9| </span><span>≤ sqrt(256)
|x + 9| </span><span>≤ +-16
-16 </span>≤ x + 9 <span>≤ 16
</span>-16 - 9 ≤ x <span>≤ 16 - 9
</span>-25 ≤ x <span>≤ 7
Since the width couldn't be negative, we can change -25 with 0,
so it become
</span> 0 < x ≤ 7

Step-by-step explanation:
multiple each numbers by 1/2
ANSWER
C. x>5
EXPLANATION
The given inequality is:
3x + 3 − x + (−7) > 6
Deal with the parenthesis first to obtain;
3x + 3 − x −7 > 6
Group similar terms to get:
3x − x> 6-3+7
Combine similar terms to get,
Divide both sides by 2 to obtain:
The correct choice is C. x>5
