telo118 [61]

Answer:

The roots (zeroes) are -1 and 527 over 3.

Step-by-step explanation:

First, you gotta do the FOIL method and multiply the values which gives u 6x^(2) -1048x - 1054. Then you find the zeroes ( the points in which the the graph intersects with the x-axis). Finally, you set y equal to zero and find the x.

  A triangular prism. The rectangular sides are 2.5 millimeters by 8 millimeters, 8 millimeters by 6.5 millimeters, and 8 millim
allsm [11]

Answer:

<u>The triangular prism shown has 2 triangular faces and 3 lateral faces.</u>

  • The triangles are on the ends, and there are three rectangular faces, which are the "lateral" faces because they're not bases.

<u>The area of one triangular face is 7.5 square millimeters.</u>

  • Area of triangle = 1/2 b*h = 1/2* 6*2.5 = 1/2*15 = <u>7.5 square millimeters</u>

<u>The surface area of the triangular prism is 135 square millimeters.</u>

  • Lateral face area = the sum of the three lateral faces. = 8*6.5 + 8*2.5 + 6*8 = 120 square millimeters
  • Surface area = 2(triangle area) + sum of lateral faces = 2(7.5) + 120 = <u>135 square millimeters</u>

Point A is located at (2, 6) and point B is located at (18, 12).
r-ruslan [8.4K]
From A-->B in a 2:3 ratio means that it's 2/(2+3) of the way up AB
So 2/5 of the x of AB = 2/5×(18-2) = 2/5 (16)
= 32/5 = 6 2/5 + the original x of A (2) = 8 2/5
2/5 of the y of AB = 2/5×(12-6) = 2/5 (6)
= 12/5 = 2 2/5 + the original y of A (6) = 8 2/5
Therefore the answer is:
(8 2/5, 8 2/5)

The perimeter of an equilateral triangle is 15x+30 units. Which expression can be used to show the side length of one side of th
lina2011 [118]
Correct Answer: Option D

An equilateral triangle is the one having all sides equal in length.

Let each side of the triangle is y units in length.

So, the perimeter of triangle will be = y + y + y = 3y units

This means,

3y = 15x + 30
3y = 3 (5x + 10)
y = 5x + 10

This means, each side of the equilateral triangle is 5x + 10 units in length.
