What is the first step in simplifying the expression -5x²(4x³ - x²)² ?

1 answer:

3 0

The first step would be the square of the parenthesis.
-5x²(4x∧6-x∧4)

4x∧6 means 4x to the sixth power.

I hope that helps.

The baseball team is purchasing 10 hot dogs, 4 hamburgers, and three loaded nachos. The snack bar will cover 60% of the cost for

Margaret [11]

Answer:

1.50

Step-by-step explanation:

X = hot dog price

Y = hamburger price

5X + 4Y = 16.50

4X + 5Y = 17.25

4(5X + 4Y = 16.50)

20X + 16Y = 66

5(4X + 5y = 17.25)

20X + 25Y = 86.25

Now subtract the equations:

20X + 16Y = 66

20X + 25Y = 86.25

9Y = 20.25

Y = 2.25

Hamburger is $2.25

4X + 5(2.25) = 17.25

4X + 11.25 = 17.25

4X = 6.00

X = 1.50

Hamburgers are $2.25

Hotdogs are $1.50
