Answer:

Rounding x = 5.52

Step-by-step explanation:

2.1x - 3.6 = 8

Add 3.6 to each side

2.1x - 3.6+3.6 = 8+3.6

2.1x = 11.6

Divide each side by 2.1

2.1x/2.1 = 11.6/2.1

x =5.523809524

Rounding x = 5.52

The factored expression ofx^3 - 7x^2 -5x +35 is (x^2 - 5)(x - 7)

<h3>What is an expression?</h3>

An expression is an algebraic term used for a mathematical statement that includes addition subtraction multiplication and division

x^3 – 7x^2 – 5x + 35

factor the given equation

x^2(x – 7) – 5(x - 7)

Factor out x - 7

(x^2 - 5)(x - 7)

Therefore, the factored expression is (x^2 - 5)(x - 7)

Help me please!!! i need help

Answer:

Step-by-step explanation:

P = 1800 + 700x - 100x²

Find x when p = $2,800

2,800 = 1800 + 700x - 100x²

- 100x² + 700x + 1800 - 2800 = 0

-100x² + 700x - 1000 = 0

- x² + 7x - 10 = 0

a = -1

b = 7

c = -10

x = -b ± √b² - 4ac / 2a

x = -7 ± √7² - 4(-1)(-10) / 2(-1)

= -7 ± √49 - 40 / -2

= -7 ± √9 / -2

= -7 ± 3 / -2

= (-7 + 3) / -2 or (-7 - 3) / -2

= -4 / -2 or -10 / -2

x = 2 or 5

x = 2 items for smaller value

x = 5 items for larger value
