Which expression is the simplest form of -(4x + y)n + 2(x - 3y)

Marina86 [1]

Answer:

$\boxed{\bold{-4nx-ny+2x-6y}}$

Explanation:

Rewrite:

= $\bold{-n\left(4x+y\right)+2\left(x-3y\right)}$

Expand $\bold{-n\left(4x+y\right): \ -4nx-ny}$

= $\bold{-4nx-ny+2\left(x-3y\right)}$

Expand $\bold{2\left(x-3y\right): \ 2x-6y}$

= $\bold{-4nx-ny+2x-6y}$

Help Please. I'm no good when it comes to math

Natali [406]

Answer: question 5 is C

Question 4 is 37.68

Question 3 is 153.86 ft sq

The question about finding the area with a diameter of 16mm is 803.84

The next one is A. 25÷8

Step-by-step explanation:

C = 2 pi r

C = 2 pi (7.8) and you get 49.01

Becuse the question is asking to round c is the best choice

When using the formula of C = 2 pi r, since radius is half of the diameter, 12÷2=6

The formula for this one is A = pi r sq

You have the radius for this one is 7

Put 7 into that and you get. ~153.94
