What is the value of this expression when x = -6 and ? 4(x2 + 3) − 2y

So you kinda forgot to mention the part where y = -1/2 but the answer is 157

Step-by-step explanation:

4(x^2 +3) - 2y

replace the variables

4(-6^2 +3) - 2 (-1/2)

use PEMDAS to solve

so parenthesis first and exponents  

4(6x6 +3) -2 (-1/2)

4(36 +3) -2 (-1/2)     (since you multiply a - by a - you get a +)

4(39) -2 (-1/2)          (again - and a - is a positive)

4(39) + 1

156 + 1

157     there it is i got a 5 of 5 on my test and have a nice day :D

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
