Yes because when you have y = -3x²-7x -6 it is just the same as f(x) = -3x² -7x - 6
12 x 5.2
Estimate:
since 5.2 is about 5, we can estimate this to:
12 x 5 = 60
Find the Product:
12
<u> x 5.2
</u> 2 4
<u> + 6 0 0
</u> 6 2 4
now add the decimal back in. In the original problem there is one decimal place (the .2 in 5.2) so we move the decimal place one over in our product
624 becomes 62.4
2 63/100
(2 and 63 hundredths)
