Answer:
D. Rx) = x2 - 4x + 10
Step-by-step explanation:
R(x)=(x-2)^2+6
R(x)=(x-2)^2+6
=(x-2)(x-2)+6
=x^2-2x-2x+4+6
=x^2-4x+10
R(x) = x^2 - 4x + 10
Option D is the answer
Answer:
Step-by-step explanation:
The first set of parentheses is unnecessary, so it can just be removed.
To remove the second set of parentheses, you must distribute the negative sign that is to its left. It changes every sign inside the parentheses.
Now you combine like terms.
So Cruz has d amount of 10$ bills.
The value of this money is 10d in dollars.
He has 3 fewer than d amount of 20$ bills.
So he has (d-3) of these 20$ bills.
The value of this money is 20(d-3) in dollars.
The total money that Cruz has is the sum of these values that we've already calculated:
10d + 20(d-3)
From there, you'll need to distribute the 20 to each term in the second set of brackets, and then combine like-terms to simplify.
Answer:
25% is the answer because 25 x 4 = 100% and 20x4= 80
~Hello There!~
19. You can use Pythagoras to figure out the missing length of the triangle
√15² - 9² = 12
(12 x 9)/2 = 54
((20 + 32) / 2) x 9 = 234
234 + 54 = 288
That's what i got ^^ Not 100% sure if its correct
20. 8 + 3 + 6 + 3 = 20
20/4 = 5
Mean = 5
Hope This Helps You!
Good Luck :)
Have A Great Day ^_^
