Answer:

n= 69 degrees

Step-by-step explanation:

total inside measure of any triangle is 180 degrees

180= n+n+42

180= 2n+ 42

2n= 180-42

2n= 138

n=69

Which monomial is a perfect cube?
neonofarm [45]

Answer:

Option (a) is correct.

1x^3 is a perfect cube.

Step-by-step explanation:

 Given : Some Monomial

We have to choose out of given monomial that is a perfect cube.

Perfect cubes are numbers that can be written as (ab)^3

So, consider 1x^3 , we know 1 can be written as 1^3

Thus,  1x^3 can be written as  1^3x^3=(1x)^3

Thus, Option (a) is correct.

Intersecting Secant (Exterior) <br> Find X =
levacccp [35]

Answer: <em>x </em>= 13

Step-by-step explanation:    the equation to solve this is:

4 × (4 + 8) = 3 × (3 + <em>x</em>)

so we solve the first half of that:

4 × (4 + 8)

4 × 12

48

now we have:

48 = 3 × (3 +<em> x</em>)

so we switch the sides to make it easier and solve

3 × (3 + <em>x</em>) = 48

divide both sides by 3

3 × (3 + <em>x</em>) ÷ 3 = 48 ÷ 3

and get

3 +<em> x</em> = 16

now subtract 3 from both sides

3 + <em>x</em> = 16

-3         -3

and finally we get

<em>x </em>= 13

hope this helped :)

State the common factor of the terms in the polynomial 5x^2 + 30x^2 - 10x. Then factor the polynomial
tatuchka [14]

Answer:

The common factor is 5x.

The factored polynomial is: 5x(7x - 2)

Step-by-step explanation:

Factor of the numbers:

The common factor of the numbers 5, 30 and 10 is 5, as it is the greater common divisor of them, as found below:

5 - 30 - 10|5

1 - 6 - 2

Factor of the exponents:

Between x^2, x^2 and x, the common factor is the x with the lowest exponent. So x

Common factor

Number multiplied by exponents, so 5x.

Factoring the polynomial:

5x^2 + 30x^2 - 10x = 5x(\frac{5x^2}{5x} + \frac{30x^2}{5x} - \frac{10x}{5x}) = 5x(x + 6x - 2) = 5x(7x - 2)

The factored polynomial is: 5x(7x - 2)
