You decide to put new carpet in your living room and family room. The combined square footage (area) of both rooms is 535 square
avanturin [10]

Answer:

The maximum square footage of the family room is 225 square feet.

Step-by-step explanation:

From statement we know the combined area and the area of the living room, the maximum area of the family room is determined by subtracting the area of the living room from the combined area. All areas are measured in square feet:

A = 535\,ft^{2}-310\,ft^{2}

A = 225\,ft^{2}

The maximum square footage of the family room is 225 square feet.

Determine the slope of the line that contains the points A(0, 2) and B(7,3). *
IgorC [24]

<h3><u>Given</u><u> </u><u>points</u><u>:</u><u>-</u></h3>
  • A (0,2)
  • B (7,3)

We know that

{\boxed{\sf Slope_{(m)}=\dfrac {y_2-y_1}{x_2-x_1}}}

  • Substitute the values

\qquad\quad {:}\longrightarrow\tt m=\dfrac {3-2}{7-0}

\qquad\quad {:}\longrightarrow\tt m=\dfrac {1}{7}

\therefore \sf Slope\:of\:the\:line\:is\:\dfrac {1}{7}

Can someone help? Solve for x
Luba_88 [7]
The answer is A) x = 9

We know this because every four sided figure has angles that measure up to 360. So we can subtract all of the angles and then use the remaining angle to solve the problem. 

360 - 90 - 90 - 99 = 81. 

So with the remaining angle being 81, we can solve for x. 

x^2 = 81
x = +/-9 

Since +9 is the only answer that makes sense in this case, x = 9.
