So first what you would have to do is separate the three triangles from the square by basically slicing the top from the bottom so now you have three identical triangles and one square then just add them all together

Perimeter of quadrilateral
aleksandr82 [10.1K]

Answer:

The answer to your question is:  14 + 2√40  = 26.6 units

Step-by-step explanation:

Data

A ( -5, 4)     B (-3, -2)     C (4, -2)     D (2, 4)

Formula

d = √(x2 - x1)² + (y2 - y1)²

Perimeter = dAB + dBC + dCD + dAD

Process

dAB = √(-3 + 5)² + (-2 - 4)²

dAB = √(2)² + (-6)²

dAB = √4 + 36

dAB = √40 units

dBC = √(4 + 3)² + (-2 + 2)²

dBC = √(7)²

dBC = √49

dBC = 7 units

dCD = √(2 - 4)² + (4 + 2)²

dCD = √(2)² + (6)²

dCD = √40 units

dAD = √(2 + 5)² + (4 - 4)²

dAD = √49

dAD = 7 units

Perimeter = √40 + 7 + √40 + 7

Perimeter = 14 + 2√40  = 26.6 units

Alenkinab [10]

Answer:

y = -x + 9.

Step-by-step explanation:

The slope = rise run

= 9 /-9

= -1.

The y intercept is at y = 9 so the equation is:

y = -x + 9.

If the side of a rectangular prism is doubled, how would this affect the area? How about the volume?
professor190 [17]

Answer:

Step-by-step explanation:

The area will be increased by 4 times  and volume will be increased by 8 times

Area of rectangular prism = 2 (lb+bh +hl)

When sides are doubled, Area = 2 (2l * 2b +2b *2h + 2h*2l)

                                                     = 4 * 2 (lb+bh +hl)

Volume  of rectangular prism = lbh

When sides are doubled,  Volume = 2l * 2h * 2b = 8 lbh

Bricks are delivered to a work site and stacked in rows and columns, forming a rectangular prism. The length of the prism is 3 f
topjm [15]
Correct so far. Finish up.
.. (x +3)(x)(x -1) = 1170
.. x^3 +2x^2 -3x -1170 = 0 . . . . . . one sign change ⇒ one positive real solution

This is a cubic equation with one positive real solution. There are several possible approaches to solving this. My favorite is to let a graphing calculator show me the solution.

You can also factor 1170 = 13*10*9, so x=10.

The width of the prism is 10 feet; the length is 13 feet; the height is 9 feet.
