Answer:

Hi there

Your answer is

NO SOLUTION!

Step-by-step explanation:

-(7a-6)=-7a-2

-7a+6 = -7a -2

+7a

6=-2

-(7a-6)=-7a-2
-7a+6=-7a-2
statement is then 6=-2
so it’s false meaning there is no solution

solve the following system of equation ​

Answers

First solve for x by doing 3x+2=-2x-8
Then move the -2x to the left side of the equation so you would add 2x which you would have 5x then subtract 2 to the right side so you would have -10 so then you would have 5x=-10 so x=-2 then plug in -2 to get the y which is -4 so it would be (-2,-4)

-7-2x=7(x+8)

What is the answer for this expression

Answers

Answer:

x=-7

Step-by-step explanation:

1. Distribute the 7 into the parenthesis: -7-2x=7x+56

2. Combine like terms by doing the opposite operation to the numbers:  -7=9x+56 (added 2x to 7x)

3. Subtract 56 to each side of the equation: -63=9x

4. To isolate the variable "x," divide each side by 9: x=-7

How many unit cubes are required to create a larger cube with edge length of 3 units? Can I also get an explanation so I know how it's done? Thanks :)

Answers

Answer:

The unit cubes that are required to create a larger cube with an edge length of 3 units is:

27 cubes.

Step-by-step explanation:

To identify the number of cubes you need to create a larger cube, you must think in the number of cubes of the length (3 cubes in this case), and use the exponent 3, because you need to form a cube. Below I'll show you:

[tex]3^{3}= 27 cubes.[/tex]

To understand it in a better form, suppose that you need a cube with an edge of 5 units, in that case, remember you use the number 5 how base and the exponent is 3, because is a cube, in that case, it would be:

[tex]5^{3}= 125 cubes[/tex]

If it wasn't a cube but a square, you must elevate to the number 2, in the case of the cube is elevated to 3, so, the unit cubes that are required to create a larger cube with an edge length of 3 units is 27 cubes.

Factor and solve each quadratic equation.

Hi does anyone wanna do a math homework assignment? it involves volume and algebra (I'm in alg2/trig)

Answers

[tex]\huge\bold\green{Answer:-}[/tex]

Area. The amount of space covered by a two-dimensional object; the amount of carpet you'd need to cover a floor would depend on the floor's area.

Perimeter. The distance around a two-dimensional object; the amount of fence you'd need to surround your yard equals the perimeter of your yard. (The perimeter of a circular object is called the circumference.

Volume. The amount of three-dimensional space inside an object; the amount of liquid inside a soda can represents the can's volume.

Surface area. Measures the amount of "skin" needed to cover a three-dimensional object, neglecting its thickness; the amount of siding you'd need to completely cover a house represents the surface area of that house's walls.

Description Formula Variables

Area of a rectangle A = l · w l = length, w = width

Perimeter of a rectangle P = 2(l + w) l = length, w = width

Area of a circle A = r2 r = radius of circle

Circumference of a circle C = 2r r = radius of circle

Volume of a rectangular solid V = l · w · h l = length, w = width, h = height

Volume of a cylinder V = r2h r = radius; h = height

Surface area of a cube SA = 6l2 l = length of side
