PLEASE HELP 100 POINTS
Karolina [17]

Step-by-step explanation:

the total surface area is the sum of the individual areas.

we have the ground area : a 6×6 square. = 36 cm²

and we have 4 equal triangles.

the area of a triangle is baseline × height / 2.

which is for each of these triangles

6 × 12 / 2 = 3 × 12 = 36 cm²

so, the total surface area of the pyramid is

36 + 4×36 = 5×36 = 180 cm²

Given the equation kx – 17 = 51 + x, where k=1, solve for X.
IgorC [24]

Answer:

  • No solution for x, when k = 1
  • x = 68/(k - 1), when k≠ 1

Step-by-step explanation:

<u>Given the equation</u>

  • kx – 17 = 51 + x, where k = 1,

<u>Solve for x:</u>

  • 1*x - 17 = 51 + x
  • x - 17 = x + 51
  • x - x = 51 + 17
  • 0 = 68,

Incorrect equation, no solution for x when k=1

<u>Solving for x when  k ≠ 1</u>

  • kx - 17 = 51 + x
  • kx - x = 51 + 17
  • x(k - 1) = 68
  • x = 68/(k - 1)

Please solve 4.16 (0.2) and show how you did it.
Alex_Xolod [135]
Okay, so how to do it, so the parentheses around the two doesn’t matter, you can times 4.16 and .2 together to get .832, it is fairly easily.
How I got it: 4.16 is on the top of .2, the decimals line up, you add a zero behind the 2 to make it a 20, now you just Times 4.16 by .20 to get .832
