<span>x(x−3)=54
x^2 - 3x - 54 = 0
(x - 9)(x +6) = 0
x - 9 = 0 so x= 9
x + 6 = 0 so x = -6
</span><span>
x = 9 (length)
so width = x - 3 = 9 -3 = 6
</span>answer
<span>length = 9
double check
Area = LxW = 9x6 = 54

Answer:
a = 30
Step-by-step explanation:
Given the following data;
a = 18
b = 3
This is a direct proportion question.
Therefore, a is directly proportional to b.
Mathematically, a = kb
First of all we would find the constant, k;
k = a/b
k = 18/3
k = 6
Now to find the value of a when b = 5
a = kb
a = 6*5
a = 30
Answer:
The Domain is -3

Step-by-step explanation:
Answer:
Distance = 54 miles (Approx)
Step-by-step explanation:
Given:
Co-ordinate of two point = (0.5,135) and (2,81)
Find:
Distance
Computation:
Distance = √(x1-x2)²+(y1-y2)²
Distance = √(2-0.5)²+(81-135)²
Distance = √2.25 + 2916
Distance = 54 miles (Approx)
12 divided by 3 is 4. the answer would be 40 as 4x10 is equal to 40
