Aworker is to paint the walls of a square room 7.55 ft high and 13.5 ft along each side. what surface area in square meters must she cover?

There are 4 walls.  Each wall has the area of length (13.5) x width (7.55).

SA = 4 ( 13.5) (7.55)

     = 407.7 ft²

Next, convert ft² to meters² (1 ft = 0.3048 meters)

407.7 ft² x ² = 37.9 meters²

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
