You need to collect the like terms (aka the letters) so 3a-5a goes together to give -2a and 2w-9w which gives -7w so the answer is -2a-7w

Remember you can add like terms exg, 3y+4y=7y 3y^2+4y^2=7y^2, but cannot add 3y^2 and 4y, or 3 and 4y so

3a+2w-5a-9w
group like trems
3a-5a+2w-9w
subtract
-2a-7w


3y^2+2w^2-y^2-w^2
group like terms (think of w^2 and y^2 as 1w^2 and 1y^2)
3y^2-y^2+2w^2-w^2
subtract
2y^2+w^2

2x+2x=4x

Write the equation of the line that has a slope of four and passes through the point 6,5
Rina8888 [55]

Answer:

4x-y=19, y=4x-19

Step-by-step explanation:

I learned a really quick way to do these in geometry.

Let's use standard form or ax+by=c.

Slope of 4:  4x - y = c.

Passes through point 6,5.

4(6) - 5 = c

c= 24-5

c=19

4x-y=19

y=4x-19

What is the volume of a right circular cone that has a height of 14.9 cm and a base with the circumference of 2.9 cm rounded to
xxMikexx [17]

Answer:

The answer to your question is  Volume = 3.30 cm³

Step-by-step explanation:

Data

Volume = ?

height = 14.9 cm

circumference = 2.9 cm

Process

1.- Calculate the radius

   circumference = 2πr

-Substitution

   2.9 = 2πr

-Solve for r

   r = 2.9/2π

   r = 1.45/π cm

2) Calculate the volume of the cone

   Volume = 1/3πr²h

-Substitution

   Volume = 1/3π(1.45/π)²(14.9)

-Simplify

   Volume = (1.04)(0.213)(14.9)

   Volume = 3.30 cm³
