Answer:

<h2><u><em>A 4 + 12+2 = 18</em></u></h2>

Step-by-step explanation:

which expression is equivalent to 4+ [4 x (5-2)] + 2?

A 4 + 12+2

B 4 + 18 + 2

C 8x3 + 2

D 8 x 5 - 1

4+ [4 x (5-2)] + 2 = 18

A 4 + 12+2 = 18

B 4 + 18 + 2 = 24

C 8x3 + 2 = 26

D 8 x 5 - 1 = 39

check

4 + [4 x (5-2)]+ 2 = 4 + 12 + 2

18 = 18

the answer is good

What is the solution to the equation 4x-6= 10x-3?
Lelechka [254]

Answer:

To solve this equation we need to get x by itself.

4x-6=10x-3, (the first step would be adding 6 to both sides.)

4x=10x+3 (the next step is the subtract ten from both sides.)

-6x=3 (Last step is the divide both sides by -6.)

x=-1/2

Hope this helps ;)

Plot the vertices (-2, -8), (-2, 2), and (8, 2).
charle [14.2K]

Answer:

  • (8, -8)
  • 100 square units

Step-by-step explanation:

The diagonals of a rectangle have the same midpoint, so for points A, B, C, D, we must have ...

  (A+C)/2 = (B+D)/2

  D = A + C - B

  D = (-2, -8) +(8, 2) -(-2, 2) = (-2+8+2, -8+2-2)

  D = (8, -8)

__

The side lengths are 2-(-8) = 10, and 8-(-2) = 10. The area is the product of the side lengths, so is 10×10 = 100 square units.

_____

<em>Comment on side lengths</em>

When the end points of one side are on the same vertical line, the length of that side is the difference of y-coordinates. When the points lie on the same horizontal line, the side length is the difference of x-coordinates.

(-2,0) And (a,3) <br> Slope 3/8
UkoKoshka [18]

Answer:

a= 6

Step-by-step explanation:

slope = (y2 - y1)/(x2 - x1)

3/8 = (3 - 0)/(a - (-2))

cross multiplying,

3(a + 2) = 3(8)

3a + 6 = 24

3a = 18

a = 18/3

a = 6
