HELP HELP HELP ILL MARK YOU BRAINLIEST

Mathematics
1 answer:
padilas [110]3 years ago

The answer would be 128z^9.

This is because when you multiply exponents with a variable (z), you keep the base the same (8z and 16z), but you add the exponents together.

What is the reason for each step in the solution of the inequality?<br><br> −2(x+3)−4&gt;4x+30
DochEvi [55]
You would have to first distribute the -2 to the x+3 which gives you -2x-6.  Then you would subtract the 4 which gives you -2x-10 on the left side.  Now you have the equation -2x-10>4x+30.  Move the 4x to the other side giving you         -6x-10>30.  Now add the 10 from the other side which leaves you with -6x>40.  Now remember when you divide by a negative in an inequality, you HAVE TO flip the sign giving you the answer of x<-20/3.

Brighten is an expression that shows how to multiply 7 * 256 using expanded form and distributive property
charle [14.2K]

I am not familiar with "brighten" but this is how you can expand and use the distributive property:

 7(256)

= 7(200 + 50 + 6)

= 7(200) + 7(50) + 7(6)

= 1400 + 350 + 30

= 1780
