Hello there!

The correct answer is option B

2x² + (4x - 6x²) + 9 - (6x + 3)

Just take them out of the parentheses

2x² + 4x - 6x² + 9 -6x - 3

Combine like terms

2x² - 6x² + 4x - 6x - 3 + 9

= -4x² - 2x + 6

Thus,

The correct answer is option B

Find the product and express your answer in scientific notation. (1.3 x 10-6)(4 x 1010)

sveticcg [70]

$(1.3\cdot10^{-6})(4\cdot10^{10})=(1.3\cdot4)(10^{-6}\cdot10^{10})=5.2\cdot10^{-6+10}\\\\=\boxed{5.2\cdot10^4}$
