Answer:
$149.50
Step-by-step explanation:
Width = x
Length = 2x - 5
Perimeter of the room = 5x
Perimeter of the room = 2(length + width)
5x = 2{(2x-5) + x}
5x = 2(2x - 5 + x)
5x = 4x - 10 + 2x
5x = 6x - 10
5x - 6x = -10
-x = -10
x = 10
Width = x = 10
Length = 2x - 5
= 2*10 - 5
= 20 - 5
= 15
Perimeter of the room = 5x
= 5 × 10
= 50 square foot
If carpet costs $2.99 a square foot, what the total cost to carpet the living room
Total cost = $2.99 × 50
= $149.50

A) £3264000.
. £1000 increased by 5000% =£51,000
. £51,000×64=£3264000
B) £6528000
. £2000 increased by 5000% =£102,000
. £102,000×64=£6528000
Step-by-step explanation
The coefficient is the number, therefore -5 and -4,
The exponent of the first x is 1 and the second x is 2, if the 2 is meant as an exponent. The first exponent of y is 1 and 5e second y is 2
