How can you find the gcf and common factors?

1 answer:

4 0

List the prime factors of each number.Multiply those factors both numbers have in common. If there are no common prime factors, the GCF is 1.
GCF and common factors are pretty much the same thing. GCF focuses only on the largest common while common focuses on them all.

For the following geometric sequence find the recursive formula: {-1, 3, -9, ...}.

vredina [299]

First term (a1) is -1

recursive formula goes like this

$a_n$ is the nth term
$a_{n-1}$ is the term before that

we normally have $a_n=f(a_{n-1})$

we see each term is multipying by -3 to get next one

so that would be
$a_n=-3*a_{n-1}$ where a1=-1

the 3rd option is correct except that it is the explicit formula

so answer is 2nd one

Evaluate the expession. x=12, y=8, z=3 4x-yz

Nataly_w [17]

Given:
 x=12, y=8, z=3

4x-yz = 4(12) - (8)(3)
4x-yz = 48 - 24
4x-yz = 24

Which statements are true about the triangle? Select all that apply.

Bogdan [553]

Answer:

The triangle is obtuse.

It is an isosceles triangle.

The angles add up to 180°.

Step-by-step explanation:

Obtuse triangles are defined as triangles with one angle obtuse angle over 90°. This triangle has an angle of 100°, so it is an obtuse triangle!

Isosceles triangles have 2 equal sides. The two orange dashes on the left and right legs of the triangle tell us they are equivalent, so this is an isosceles triangle as well!

Finally, all triangles add up to 180°! We can prove this by adding the angles.

40° + 40° = 80°

100° + 80° = 180°
