Step-by-step explanation:

SA = 12(3 + 4 + 5) + 2(½ × 3 × 4)

SA = 12(12) + 2(2 × 3)

SA = 144 + 2(6)

SA = 144 + 12

SA = 156 cm²

Therefore

Surface area of prism is 156 cm². Option D

Answer:

  • D. 156 cm²

Step-by-step explanation:

<u>The full surface area is:</u>

  • S = Ph + 2B = (3 + 4 + 5)*12 + 2(1/2*3*4) = 144 + 12 = 156 cm²

Correct choice is D

The coordinates of points M,N, and P are ....
Rainbow [258]

Answer:

(-1, -1) Let me know if the explanation didn't make sense.  

Step-by-step explanation:

If we graph the three points we can see what looks like a quadrilateral's upper right portion, so we need a point in the lower left.  This means M is only connected to N here and P is only connected to N.  So we want to find the slope of these two lines.

MN is easy since their y values are the same, the slope is 0.

NP we just use the slope formula so (y2-y1)/(x2-x1) = (-1-3)/(5-4) = -4.

So now we want a line from point M with a slope of -4 to intersect with a line from point P with a slope of 0.  To find these lines  weuse point slope form  for those two points.  The formula for point slope form is y - y1 = m(x-x1)

y-3 = -4(x+2) -> y = -4x-5

y+1 = 0(x-5) -> y = -1

So now we want these two to intersect.  We just set them equal to each other.

-1 = -4x -5 -> -1 = x

So this gives us our x value.  Now we can plug that into either function to find the y value.  This is super easy of we use y = -1 because all y values in this are -1, so the point Q is (-1, -1)

Emma scored 4 points more than twice number of points teagan scored. Emma scored 3 points. How many did teagan score
Snowcat [4.5K]
Let's write T for Teagan's score and E for Emma's score.
Also, let's write an equation

E = 2T + 4
E = 3
2T + 4 = 3
subtract 4 from both sides
2T = -1
divide both sides by 2
T = -1/2

To see of this is correct:
2T + 4 = 3
2(-1/2) + 4 =?= 3
-1 + 4 =?= 3
3 = 3

Hope this helps
