Divide: 8a^8–20a^6 +2a^4/
4a^3

Answers

Answer 1

Answer:

This comes out as 2a⁵ - 5a³ + a / 2

Step-by-step explanation:

We could use long division for this but since the denominator is a single term, we can just divide each term by that individually

[tex]\frac{8a^8 - 20a^6 + 2a^4}{4a^3} \\\\= \frac{8a^8}{4a^3} - \frac{20a^6}{4a^3} + \frac{ 2a^4}{4a^3} \\\\= 2a^5 - 5a^3 + \frac{1}{2}a[/tex]

Answer:

  2/3

Step-by-step explanation:

There are a couple of different ways that division of fractions can be done.

1) "invert and multiply"

  [tex]\dfrac{14}{15}\div\dfrac{7}{5}=\dfrac{14}{15}\times\dfrac{5}{7}\\\\=\dfrac{14}{7}\times\dfrac{5}{15}=\boxed{\dfrac{2}{3}}[/tex]

2) use the numerators when the denominators are the same

  [tex]\dfrac{14}{15}\div\dfrac{7}{5}=\dfrac{14}{15}\div\dfrac{21}{15}\\\\=\dfrac{14}{21}=\boxed{\dfrac{2}{3}}[/tex]

If mGHJ = 27 and mGHK = 87, what is the measure of mJHK

Answers

Answer:

114 degrees

Step-by-step explanation:

From the letters that describe the rays, these two angles are adjacent to each other, and therefore, if the measure of one is 27 degrees and that of the other one is 87 degrees, then the larger angle defined by the two rays (HJ and HK) with common vertex H would be:

m<JHK = 27 degrees+ 87 degrees = 114 degrees

What is  square pyramid?

A square pyramid has a square base and four lateral faces in geometry. A pyramid is a polyhedron with a base and three or more triangular faces that meet above it . A square pyramid, also known as a pentahedron, is a three-dimensional geometry with a total of five faces.

How to solve?

As ancient pyramid models were in shape of square pyramid hence we apply

[tex]A = a(a + \sqrt{ (a^{2} + 4h^{2} ))}[/tex]

where a =25cm

and h=30 cm

[tex]A = 25(25 + \sqrt{ (25^{2} + 4(30^{2}) ))}[/tex]

=25(25+65)

=2250[tex]cm^{2}[/tex]

Hence Cassie need to make the model is 2250[tex]cm^{2}[/tex]

Given: Point C is the midpoint of AB¯¯¯¯¯.

Prove: AC=25



Drag and drop reasons into the boxes to correctly complete the proof.



Statement Reason
Point C is the midpoint of AB¯¯¯¯¯. Given
AC=7x−10; CB=3x+10 Given
AC=CB Definition of midpoint
7x−10=3x+10 Response area
4x−10=10 Response area
4x=20 Addition Property of Equality
x=5 Response area
AC=7(5)−10 Substitution Property of Equality
AC=35−10 Simplify.
AC=25 Simplify.

Answers

Answer:

See proof below

Step-by-step explanation:

If C is the midpoint of AB, then AC = CB

Given

AC=7x−10;

CB=3x+10

Then 7x - 10= 3x+10

Add 10 to both sides

7x-10+10 = 3x +10+10

7x = 3x + 20

7x - 3x   = 10+10

4x = 20

x = 20/4

x = 5

Get AC

AC = 7x - 10

AC= 7(5) - 10

AC = 35-10

AC = 25 (Proved)
