Answer:

B: 304in^2

Step-by-step explanation:

One triangle face: (8)(15) ÷ 2 = 60

Four triangle faces: 60 x 4 = 240

Bottom Face: (8)(8) = 64

Total Surface Area: Four triangle faces + Bottom Face

Total Surface Area: 240 + 64

Total Surface Area: 304in^2

Answer:

The solution of this system of equations is (3 , -8)

Step-by-step explanation:

The given system is

x + 2y = -13

12x + 5y = -4

We make x the subject of the first equation and put it into the second:

x =  - 13 - 2y

We put this expression for x into the second equation

12(-13-2y)+5y=-4

-156-24y+5y=-4

-24y+5y=-4+156

-19y=152

y=-8

We substitute y=-8 into x=-13-2y to get:

x =  - 13 - 2( - 8) = 3

The solution of this system of equations is (3 , -8)

The triangles are congruent by the SSS congruence theorem.
NISA [10]

The rigid transformations that maps ΔABC onto ΔFED by reflection then translation.

The correct option is (B).

<h3>What is Translation?</h3>

Translation is also another form of transformation whereby all the points of a figure are shifted at exactly the same distance and in the same direction without being resized, reflected nor rotated.

given:

ΔABC ≅ ΔFED are congruent by the SSS Congruence Theorem.

Hence, the rigid transformations that maps ΔABC onto ΔFED by reflection then translation.
