Solve for x: 15x2 = x+2 x2 is x to the second power

Mathematics

Greeting!

15x² = x + 2
15x² - x -2= 0
Factor left side
(5x-2)(3x+1)=0
Set factors equal to 0
5x - 2 = 0 or 3x + 1 -0
x = 2/5 or x= -1/3

I hope that helps!

Ratio and proportion

height :legnth of shadow=56:49 (man's shadow)
we assume the ratio is the same for the tower thing (obelisk)

so
56:49=x:28
conver tto fraction
56/49=x/28
times both sides by 28
1568/49=x
32=x
answer is 32ft

In applying the first-in, first-out method of costing inventories, if 8,000 units that are 30% completed are in process on June
ValentinkaMS [17]

Answer:

The FIFO method (first-in, first-out) considerate the amount of processing at the beginning and the end of the period. This two moments are converted in equivalent units as it follows:

On June 1, the 30% of 8000 units are completed: 0.30(8000) = 2400 completed units.

During June, 28,000 units are completed.

On June 30, the 80% of 4000 units are completed: 0.80(4000) = 3200 units completed. But these units are remaining from June 1. So, the actual amount of equivalent units from June 1 and June 30 is 3200 - 2400 = 800 units.

Then, we some the total of equivalent units of production 28000 + 800 = 28800.

<em>Therefore, the answer is </em><em>false</em><em>, because is more than 28600.</em>

Determine the number of lines of symmetry and the number of rotation symmetries for each of the following sea organisms.
Alex777 [14]

There are 9 lines of symmetry and infinite rotational symmetries in first figure,4 lines of symmetry and no rotational symmetries in second figure,6 lines of symmetry and infinite rotational symmetries in third figure,1 line of symmetry and infinite rotational symmetries in fourth figure.

Given four figures.

We are required to find the number of lines of symmetry and rotational symmtries.

Symmetry lines are those lines which act as shape in such a way that both parts are like mirror image.

Rotational symmetry is the property that a shape has when it looks same after some turn.

  • There are 9 lines of symmetry and infinite rotational symmetries in first figure.
  • There are 4 lines of symmetry and no rotational symmetries in second figure.
  • There are 6 lines of symmetry and infinite rotational symmetries in third figure.
  • There is 1 line of symmetry and infinite rotational symmetries in fourth figure.

Hence there are 9 lines of symmetry and infinite rotational symmetries in first figure,4 lines of symmetry and no rotational symmetries in second figure,6 lines of symmetry and infinite rotational symmetries in third figure,1 line of symmetry and infinite rotational symmetries in fourth figure.

The area of a rectangle is 42 square inches. the length is 7 inches.what is the perimeter of the rectangle?
andrew11 [14]

In order to find the perimeter, we need to have the length and the width. We are told that the area of the rectangle is 42. We will use that in the area formula, length times width, to solve for w. 42 = 7w so w = 6. The length is 7 and the width is 6. The perimeter formula for a rectangle is P = 2L + 2W. We have both the length and the width now, so we fill in accordingly. P = 2(7) + 2(6). And P=14+12. The perimeter then is 26 inches.
