Answer:

see below

Step-by-step explanation:

<1 and <2 are supplements

<3 and <4 are supplements

<1 is congruent to <4

∠1 + ∠2 = 180     definition of supplementary angles

∠3 + ∠4 = 180    definition of supplementary angles

 ∠1 + ∠2 = ∠3 + ∠4    transitive property of equality

 ∠1 = ∠4                      given

 ∠1 + ∠2 = ∠3 + ∠1     substitution property of equality

∠2 = ∠3                     subtraction property of equality

∠2 ≅ ∠4                   definition of congruent angles

This prism has a surface area of 172 cm². What would the surface of the prism be if each dimension was tripled? ( Scale factor i
Alex787 [66]

Answer:

1356 cm²

Step-by-step explanation:

Each dimension gets multiplied by 2, so the new dimensions are

changed from 2x8x7 to 6x24x21

There are 6 faces to the prism,

The area of the front and back are 6x21 = 126.  There are 2 of them for a total area of 126x2 = 252 cm²

The are of the left and right sides are 24x21 = 504.  There are 2 of them for a total area of 504x2 = 1008 cm²

The area of the top and bottom are 6x24 = 144, there are 2 of them for a total area of 144x2 = 288 cm²

The total surface area is 252 + 1008 + 96 = 1356 cm²

Solve the equation for y<br><br><br> 4x+7y=28 <br><br> y=
bogdanovich [222]
Let's solve for y.

4x+7y=28

Add -4x to both sides.

4x+7y+−4x=28+−4x

7y=−4x+28

Divide both sides by 7.

7y/7=−4x+28/7

y=−4/7x+4
