It's a binomial times a binomial, so you FOIL
First multiply the First numbers
3z*z = 3z(^2)
Then multiply Outers:
3z* -4 = -12z
Nest, Inners:
9*z = 9z
Finally, the Lasts:
-4*9 = -36
Then, throw it all together in descending order, starting with the variable of highest degree to lowest:
3z^2 - 12z + 9z - 36
Last of all, simplify coefficients with like terms and you're good to go:
3z^2 - 3z - 36
Hope this helps!
For a...
Split the figure into 2 different shapes. We’re gonna split it where the 19 line is. So now you have sort of a square and a rectangle. You need to find the area of each. If the line in bottom is 35 and the rectangle top line is 19, just subtract 19 from 35 and you get the bottom line of your square. Same for the 25 on the left of the whole figure. Do the same with figure band divide where the 7 line is. Find the area of each
20 beacause 20 x 2 = 40 and twice as many means 2 x ....

please take a closer picture. :)
Step-by-step explanation:
Answer: No, I do not believe that there is enough convincing evidence to proof that he can control the dice.
When you roll a die, there is a 1/6 probability that you will roll a 6. If you multiply 50 by (1/6) you would expect your friend to roll at least 8 sixes.
He only rolled 3 more sixes than was expected. I would have him roll 50 more times at least to see how he does.
