Answer:

Step-by-step explanation:

Area of Square = (x+5)²= x² + 10x + 25

Area of rectangle = 2x  * x  = 2x²

area of rectangle + 1 = Area of square

 2x² + 1 = x² + 10x +25

2x² + 1 - x² - 10x - 25 = 0

x²  - 10x - 24 = 0

(x - 12) (x + 2) = 0

x - 12 = 0   ;   Ignore x + 2  because length wont come in negative

x = 12

Answer:

No real solutions.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2x^2+x+5=2x+1

Step 2: Subtract 2x+1 from both sides.

2x^2+x+5−(2x+1)=2x+1−(2x+1)

2x^2−x+4=0

Step 3: Use quadratic formula with a=2, b=-1, c=4.

x= −b±√b2−4ac/2a

x= −(−1)±√(−1)^2−4(2)(4)/2(2)

x= 1±√−31/4

iren [92.7K]

The correct answer is:

A line that crosses segment at right angles while dividing the segment in half is called <u>a perpendicular bisector</u>

Step-by-step explanation:

A bisector is a line that divides a line segment in two equal parts. A perpendicular bisector is a line that is perpendicular to given line segment and passes through the mid-point of the line segment. It can also be said as that the line perpendicular to a line segment that divides the lines in half is called the perpendicular bisector.

The correct answer is:

A line that crosses segment at right angles while dividing the segment in half is called <u>a perpendicular bisector</u>

Keywords: Perpendicular, bisector
