tiny-mole [99]

Yes they are the same because if you walk to the merry go round from the water slide it would be 10 of those squares and if you count from the merry go round to the water slide it would also be 10 squares

Express the product of 2x^2+6x-8 and x+3 in standard form

Radda [10]

The answer is 2x³ + 12x² + 10x - 24

(2x² + 6x - 8)(x + 3) = x(2x² + 6x - 8) + 3(2x² + 6x - 8) =
= 2x³ + 6x² - 8x + 6x² + 18x - 24 =
= 2x³ + (6x² + 6x²) + (-8x + 18x) - 24 =
= 2x³ + 12x² + 10x - 24
