Solve the following equation (If possible please show work)
natima [27]

Answer:

x = 1.8

Step-by-step explanation:

2 ( 4x-3) - 8 = 4-2x

Distribute

8x -6 -8 = 4- 2x

Combine like terms

8x - 14 = 4 - 2x

Add 2x to each side

8x - 14 +2x = 4-2x+2x

10x-14 = 4

Add 14 to each side

10x-14+14 = 4+14

10x = 18

Divide by 10

10x/10 = 18/10

x = 1.8

How do I find the surface area of a rectangular prism
uranmaximum [27]
Here you are the Surface Area of a Rectangular Prism = 2ab + 2bc + 2ac

 (a, b, and c are the lengths of the 3 sides)

In words, the surface area of a rectangular prism is the area of the six rectangles that cover it. But we don't have to figure out all six because we know that the top and bottom are the same, the front and back are the same, and the left and right sides are the same.

The area of the top and bottom (side lengths a and c) = a*c. Since there are two of them, you get 2ac. The front and back have side lengths of b and c. The area of one of them is b*c, and there are two of them, so the surface area of those two is 2bc. The left and right side have side lengths of a and b, so the surface area of one of them is a*b. Again, there are two of them, so their combined surface area is 2ab.

Plz I need help with geometry homework FIND THE ANGLES
Talja [164]

Answer:

  1. a = 36°
  2. b = 36°
  3. c = 72°
  4. d = 72°
  5. e = 108°
  6. f = 16°
  7. g = 74°
  8. h = 70°

Step-by-step explanation:

You are expected to know and make use of the following relations:

  • vertical angles are congruent
  • angles of a linear pair are supplementary
  • angles of a triangle sum to 180°
  • alternate interior angles are congruent (at parallel lines)
  • corresponding angles are congruent (at parallel lines)
  • acute angles of a right triangle are complementary
  • base angles of an isosceles triangle are congruent

__

For this problem, it isn't always easiest to work the questions in order. It is best to start with the angles easiest to find from those given.

  b and 144° are a linear pair, so b = 180° -144° = 36°

  a and b are alternate interior angles, so a = b = 36°

  2d and 144° are corresponding angles, so d = 144°/2 = 72°

  e is the apex angle of an isosceles triangle with base angles 36°, so is 180° -2(36°) = 108° = e

  f and 164° are a linear pair, so f = 180° -164° = 16°

  g and f are complementary, so g = 90° -16° = 74°

  g+h is a vertical angle with 144°, so is congruent to that. h = 144° -74° = 70°

  c is the base angle of an isosceles triangle with b as the vertex angle. That means c = (180° -36°)/2 = 72°
