Answer:

First of all you have to know that,

( + ) × ( + ) = ( + )

( - ) × ( - ) = ( + )

( + ) × ( - ) = ( - )

Now let us solve now.

#1

- ( 5x + 3y + 5z ) + 6x

- 5x - 3y - 5z + 6x

- 5x + 6x - 3y - 5z

x - 3y - 5z

#2

- ( 4x - 5y + 8 )

- 4x +5y - 8

#3

6t - ( 5r - 4p + 9 )

6t - 5r + 4p -9

#4

-2 ( 3x + 7y )

- 6x - 14y

Hope this helps you :-)

Let me know if you have any other questions :-)

Which number logically follows this series 4 6 9 6 14 6?

I would say 19.
If you take out the 6s and just look at the rest you have 4, 9, 14.
It is adding 5 each time and just have a 6 between each one.
So logically I would say 19.

A cube has a lateral area of 676 square feet.<br> What is the side length of the cube?
sp2606 [1]

Answer:

13 ft.

Step-by-step explanation:

Lateral Surface area of a cube is the area of 4 sides, front side, back side, left side face and right side face.

It can be seen seen from the attached figure as well.

Each face in a cube is a square. And each side in the cube is equal.

So, Lateral surface area is nothing but 4 \times area of a square.

And we know that area of a square = side^{2}.

Hence, Lateral surface area = 4 \times side^{2}

As per question:

4 \times side^{2} = 676

side^2 = 169 \\\Rightarrow side = 13

Hence, side length of cube = 13 feet.
