2(6)-2x=3<br> CN someone answer? Use distributive property

Mandarinka [93]

Answer:

I think this is what you want:

2(6)-2x=3

We then see that 2(6) and 2(x) have two in common as a "coefficient" you could say, so we distribute and put parentheses around it.

2(6-x)=3

6-x=3/2

-x=-9/2

x=9/2

The surface area of a cube is 600 square inches. What is the area of one of its faces?

wel

Answer:

Area of one face of the cube is $100 inches^2$

Step-by-step explanation:

A cube is a three dimensional figure that has all of its sides equal.

A cube has six square faces:

Surface area of the cube = $6a^2$

where 'a' is the side length of the cube:

Area of one face of a cube= $a^2$

For surface area of the whole cube: 500 square inches

$6a^2=600$

Dividing by '6' both sides;

$a^2=600/6\\\\$

$a^2=100inches^2$

Area of one face of the cube is $100 inches^2$

E(7, 3), F(7, -3), and G(-6, -3) are three vertices of rectangle EFGH. What are the coordinates of the fourth vertex, H?

____ [38]

Answer:

D) (-6, 3)

Step-by-step explanation:

In rectangle, the opposite sides are equal and each angle measures 90 degrees.

Therefore, draw the parallel sides and find the vertex of the fourth coordinate.

Here the vertex, H = (-6, 3)

Thepotemich [5.8K]

Answer:

Step-by-step explanation:

4y - 2(5 - y + 4) = 4y - 2(9 - y)

= 4y + 9*(-2) - y *(-2)

= 4y - 18 + 2y {Combine like terms 4y and 2y}

= 6y - 18

6y - 18 = 6*y - 6*3

= 6(y - 3)

6y- 18 = 2 *3y - 2*9

= 2(3y -9)

2(3y - 9) and 6(y- 3 ) are equivalent to 4y - 2(5- y +4)

Others are not equivalent
