What is the percent of change in 6 yards to 36 yards
BaLLatris [955]

Answer:

The percent of change in 6 yards to 36 yards is 500% .

Step-by-step explanation:

Formula

Percentage = \frac{Change\ in\ value\times 100}{initial\ value}

Where

Change in value = Final value - initial value

As given

The percent of change in 6 yards to 36 yards.

Final value = 36 yards

initial value = 6 yards

Change in value = 36 - 6

Put in the formula

Percentage = \frac{30\times 100}{6}

Percentage = \frac{3000}{6}

Percentage = 500%

Which expression is equivalent to (x2 +9x – 1)(-4x + 3)? brainly
Andrews [41]

Answer:

- 4x³ - 33x² + 31x - 3

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

x²(- 4x + 3) + 9x(- 4x + 3) - 1 (- 4x + 3) ← distribute all 3 parenthesis

= - 4x³ + 3x² - 36x² + 27x + 4x - 3 ← collect like terms

= - 4x³ - 33x² + 31x - 3
