Answer:

yes

Step-by-step explanation:

In front of every variable there is an invisible one which is being multiplied by the variable. This doesn't affect the variable because anything times one is still itself. The most common usage of the one is when combining like terms such as x+x. Since the equation is really 1x+1x, it would be 2x.

Answer:

w = 33.94 ft

Step-by-step explanation:the roof takes the shape of a right angle. The top of the roof is a right angle. To find the width of the house, which is the hypotenuse of the triangular roof, we would apply pythagorean theorem.

Thus:

$w^2 = 24^2 + 24^2$
