Answer:

= -8x +24w +16

Step-by-step explanation:

The factor outside multiplies each term inside parentheses.

-8(x -3w -2) = (-8)(x) +(-8)(-3w) +(-8)(-2)

= -8x +24w +16

Hello, that number before the parenthesis means we have to multiply the number outside the parenthesis for the one inside it.

So, the first one 9(1/3) it's easy. We can write 9 as 9/1 to semplify our work.

You have to cross multiply. When cross multiplying, you can simplify numbers. 9 and 3 can be both divided for 3.

You get 3/1 × 1/1 = 3

It equals to 3

Then, 4(2.6) = 4 × 2.6 = 10.4

2(-3) = +2 × (-3) = -6

When you multiply a positive number for a negative one, you'll always get a negative number.

Sum all the results.

3 - 10.4 - 6 = 3 - 10.4 - 6 = - 13,4

Final answer: -13,4

In the diagram, which angles are vertical angles? Select

Mumz [18]

Answer:

∠ABE and ∠CBD

∠ABC and ∠EBD

Step-by-step explanation:

we know that

Vertical Angles are the congruent angles opposite each other when two lines cross

In this problem we have that

m∠ABE=m∠CBD ----> by vertical angles

m∠ABC=m∠EBD ----> by vertical angles

therefore

The angles that are vertical angles are

∠ABE and ∠CBD

∠ABC and ∠EBD

If m(x)=x 5/x-1 and n(x) = x – 3, which function has the same domain as (m*n)(x)

Tatiana [17]

Answer:
m(x) has the same domain as (m*n)(x)

Explanation:
1- For m(x):
m(x) is a fraction. This means that the denominator cannot be zero, otherwise, the fraction would be undefined.
The denominator of m(x) would be zero at x = 1.
This means that the domain of m(x) can be any real number except 1

2- For n(x):
The value of x in n(x) can be any number. This is because there is no value that would make n(x) undefined.
This means that the domain of n(x) is all real numbers

3- For (m*n)(x):
(m*n)(x) = m(x) * n(x) = $\frac{x-5}{x-1} *(x-3) = \frac{(x-5)(x-3)}{(x-1)}$

We can note that the product is also a fraction. This means that the denominator cannot be zero.
The denominator here will be zero at x = 1.
This means that the domain of (m*n)(x) is all real numbers except 1.
This is the same as the domain of m(x)

Hope this helps :)
