Answer:
41
Step-by-step explanation:
With n being 3, 3 would multiply by 2 (and become 6), and since it's going to be squared, your new equation will be "5+6^2". 6 squared is 36, and 5 being added to 36 results in 41. Therefore, your answer is 41.
Answer:
C. -7x^2 - 28
Step-by-step explanation:
Firstly simplify the bracket before doing anything;
4x(3x - 7) = 12x^2 - 28x
then go back to the question and substitute the expression(12x^2 - 28x) on the bracket and then work out the question;
12x^2 - 28x -19x^2...then group the values with the same exponent of x,
(12x^2 - 19x^2) - 28x
; -7x^2 - 28x
Answer:
Step-by-step explanation:
Red =x Blue = y
1) 4x + 6y = 180
2) x + y = 40
solve for x in eq. 2 and plug into eq. 1
2a) x=40-y
1a) 4(40-y) + 6y = 180
160-4y +6y = 180
2y=20
y=10
plug into eq. 2
x + 10 =40
x=30
30 red packages
;) maybe a late Christmas gift.. :D

i HOPE U UNDERSTOOD!! :)
I could give you a formula but it's really simple. Every 5 Minutes the Truck empties 30 cubic feet, thus 0=190, 5=160 etc, your Answer is 10 Minutes until the truck empties to 40 cubic feet.
