Answer: ( P - 10 )/12, (2x + 5)(4x + 1)
Step-by-step explanation:
The length of the rectangle = 4x + 1,
The breadth = 2x + 5
Formula for finding perimeter of a rectangle, = 2( L + B )
Now, substitute for L and B in the formula, open the formula and simplify,
= 2(4x + 1 + 2x + 5 )
= 2(6x + 5 )
= 12x + 10
Therefore, the perimeter (p)of the rectangle, = 12x + 10.
If P = 12x + 10
12x = P - 10
x = ( P - 10 )/12
Area of a rectangle = L x B
=( 4x + 1 )( 2x + 5)
We therefore open the brackets
(4x + 1)(2x + 5)= 4x X 2x + 4x X 5+ 1 X 2x + 1 X 5
= 8x² + 20x + 2x + 5
A = 8x² + 22x + 5
A = (2x + 5)(4x + 1)

Step-by-step explanation:
If minus stands before parenthesis the sign in the parenthesis changes to the opposite
Answer:
A=24 sq ft
P=20 ft
Step-by-step explanation:
To make this easier, separate the triangle and the rectangle. To find the area of the triangle multiply the bases and the height and then divide the answer by. So,
(6x4)/2
(24)/2
A=12
The base of the triangle is the same as the base on the rectangle. To get the perimeter, add the 3 side values up.
5+5+6
P=16
For the rectangle, to get the area, just multiply the base value and the height value. So,
(6x2)
A=12
To get the perimeter, add all the side values up. So,
6+6+2+2
P=12
Add the 5 sides of the pentagon up for the perimeter.
5+5+2+2+6
P=20
And finally, add the area of the triangle and the rectangle to get the area of the pentagon.
12+12
A=24
Answer:
x is less than oe equal to 12
