Answer:

Step-by-step explanation:

2 surfaces that are 5x7

2 surfaces that are 4x7

and the top and bottom that are 4x5

2*5*7 = 70

2*4*7 = 56

2*4*5 = 40

total surface is 166 $cm^{2}$

Answer:

166 square centimeters

Step-by-step explanation:

Surface area of a rectangular prism can be found by finding the area of each of the six surfaces of the prism. Remember that opposite sides on a rectangular prism are equal to each other, as they have the same side lengths. Because of this, the equation for surface area can be described as: 2lw + 2lh + 2wh. In this case, the length l is represented by 5cm, the width w is 4cm, and the height h is 7 cm. Now you can solve for the surface area:

SA = 2lw + 2lh + 2wh

SA = 2(5 x 4) + 2(5 x 7) + 2(4 x 7)

SA = 2(20) + 2(35) + 2(28)

SA = 40 + 70 + 56

SA = 166

Recall that units of area are given as square units, and the measure of this rectangular prism is given in centimeters. The answer is then given in square centimeters.

SA = 166 square centimeters

Help me please, I really suck at math and I need help

Murrr4er [49]

Although A is correct, C is the correct answer. If you don't get a problem like this, try to draw some of the shapes out and then draw a symmetrical line down the middle to find out if it is symmetrical.

How to graph y=-4|x+2|-5

Elina [12.6K]

$y= -4|x+2| -5 \\ \\x= -6 \Rightarrow y=-4|-6+2|- 5= -4|-4|- 5= -4*4 -5 =\\ \\=-16-5=-21\\ \\ \\x= -4\Rightarrow y=-4|-4+2|- 5= -4|-2|- 5= -4*2 -5 =\\ \\ =-8-5=-13\\ \\ \\x= -2 \Rightarrow y=-4|-2+2|- 5= -4|0|- 5= -4*0 -5 =-5\\ \\ \\x= 0 \Rightarrow y=-4|0+2|- 5= -4|2|- 5= -4*2 -5 =-8-5=-13\\ \\ \\x= 2 \Rightarrow y=-4|2+2|- 5= -4| 4|- 5= -4*4 -5 =-16-5=-21$
