Answer:

The lengths of the diagonals is 22.

Step-by-step explanation: Since the shape is a rectangle, the diagonals are congruent, we can form the equation 3x+7=5x-3.

Solve for x; 2x=10-->x=5.

Plug 5 into one of the equations. 3(5)+7=22. 5(5)-3=22

Hope this helps!

Answer:

y = 7x -48

Step-by-step explanation:

Your answer is correct. You just need to write it in the box without the "y =".

The 2-point form of the equation for a line is ...

y = (y2 -y1)/(x2 -1x)(x -x1) +y1

y = (8 -(-6))/(8 -6)(x -6) +(-6)

y = 14/2(x -6) -6

y = 7x -42 -6

y = 7x -48

You probably want your answer to look like ...

$y=\boxed{7x-48}$

Answer:

144

Step-by-step explanation:

48 ÷ 4 (which is how many sides a square has) is 12

So 12x12 because l×w (length and width) and all sides of a square are equal

So the answer would be 144
