Multiply. 32√⋅28√⋅3√⋅6√ in simplest radical form, in the box.
PolarNik [594]

Answer:  48\sqrt{7}

Step-by-step explanation:

Given expression, \sqrt{32} \times \sqrt{28}\times \sqrt{3}\times \sqrt{6}

= √(4×8)×√(4×7)×√3×√(3×√2)

= √4×√8×√4×√7×√3×√3×√2 ( because √(m×n)=√m×√n)

=√4×√4×√8×√2×√7×√3×√3

=4×√(4×2)×√2×√7×3

=4×√4×√2×√2×√7×3

=4×2×2×√7×3

=48√7

Thus,\sqrt{32} \times \sqrt{28}\times \sqrt{3}\times \sqrt{6}=48\sqrt{7}

James currently has $215 in a savings account. Every month, he deposits an additional $45 into his account. James had to replace
Romashka-Z-Leto [24]

Answer:

James still owes 1,261 dollars after 12 months

Step-by-step explanation:

<u>Second attempt :P</u>

James currently has 215 dollars, every month for 12 months, he deposits 45 dollars into his account

215 + 12 x 45

215 + 540 =755

Now we know how much money James will have after 12 months,  we need to find out how much he will owe.

James has to pay 168 per month for 12 months

168 x 12 = 2016

After 12 months the total amount James owes will be 2,016 dollars.

He makes 755 for the whole 12 months

2,016 - 755 = 1,261

James still owes 1,261 dollars after 12 months
