anonymous · Answer

I dont see where it shows how to solve it or the answer.

amistre64 · Answer

to solve it you simply multiply it together.....

anonymous · Answer

How do you do that?

amistre64 · Answer

by applying the distributive property thru the problem

amistre64 · Answer

8(6) = 48
(5+3)(2+4)  = 48

(5+3)(2) + (5+3)(4) = 48

5(2) + 3(2) + 5(4) + 3(4) = 48

10 + 6 + 20 + 12 = 48

16 + 32 = 48

48 = 48

thats how we distribute....

anonymous · Answer

So the answer is 48?

anonymous · Answer

no he was just giving you an example .  you have to do 4 multiplications

anonymous · Answer

$$(6x+3)(2x^2-5)$$

anonymous · Answer

$$6x\times 2x^2+6x\times -5+3\times 2x^2+3\times -5$$

anonymous · Answer

4 multiplications .  then of course you actually do the multiplications as in 
$$6x\times 2x^2=12x^3$$
$$6x\times -5=-30x$$
$$3\times 2x^2=6x^2$$
$$3\times -5=-15$$

anonymous · Answer

so your answer is 
$$12x^3-30x+6x^2-15$$
