Four less than the product of a number and 8 is twice the sum of the number and 10 what is the number

x=4

Step-by-step explanation:

Four less than the product of a number and 8:

8x−4

is twice the sum of the number and 10, so

8x−4=2(x+10)

Simplify.

8x−4=2x+20

Add 4 to both sides, which is

8x=2x+24

Subtract 2x from both sides:

6x=24

Divide 6 from both sides to isolate the x

x=4

-how I got 20

8x-4=2(x+10) x=8 so 8+10=18 18+2=20

also sorry for posting the answer in the comments and then making an answer after you saw i just wanted da points and hope it helped you :)

We conclude that ''rectangle D'E'F'G' is larger than rectangle DEFG because the scale factor is greater than 1''.

Step-by-step explanation:

We know that when an object is dilated by a scale factor, the shape of the original size does not change, but the size of the original object tends to change depending upon the value of a scale factor.

For example,

Given that Rectangle DEFG is dilated with the origin as the center of the dilation using the rule (x,y) --> (3.5x, 3.5y) to create rectangle D'E'F'G'.

Given the scale factor = 3.5

As the scale factor > 1

Thus, the rectangle D'E'F'G' is larger than the rectangle DEFG.

Therefore, we conclude that ''rectangle D'E'F'G' is larger than rectangle DEFG because the scale factor is greater than 1''.
