Answer:
15[tex]a^{6}[/tex] + 15[tex]a^{2}[/tex]b + 10[tex]a^{2}[/tex]
Step-by-step explanation:
In order to find the area of a rectangle, you have to multiply the length by the width. Using the distributive property, we see:
5[tex]a^{2}[/tex](3[tex]a^{4}[/tex] + 3b + 2) = 15[tex]a^{6}[/tex] + 15[tex]a^{2}[/tex]b + 10[tex]a^{2}[/tex]
(note that when multiplying variables with like bases, you add the exponents, not multiply them)
