A rectangle is a quadrilateral and its area is expressed as the product of its length and width. From the given, we have:
Length = x + 2
Width = 2x - 5
Area = 54 cm^2
Area = Length x Width
Substituting the values,
Area = (x + 2) ( 2x-5) = 54
54 = 2x^2 - x - 10
2x^2 - x - 64 = 0
We can see that the equation above is a polynomial with a degree of 2 therefore we can usethe Quadratic Formula to solve for x. The quadratic formula will solve two values of x.
x1 = (-b + (√b^2 - (4ac))/ 2a = 5.91
x2 = <span>(-b - (√b^2 - (4ac))/ 2a = -5.41
Since, for this case, the value x should not result to a negative value for both dimensions thus x is equal to 5.91.</span>
Answer:
the answer is $33.04
Step-by-step explanation:
since the total cost was $165.20 and we need to find the cost of one video game we will divide the the total ($165.20) with 5 video games and you will get $33.04

Answer:
3cm
Step-by-step explanation:
those double hashes on those 5 sides mean they are equal. so essentially you have 5 sides that measure 3/10cm and one side that measures 1 1/2cm.
3/10 * 5 = 15/10 = 1 1/2cm
1 1/2cm + 1 1/2cm = 3cm
