I got the answer 8x^3+1 by putting the values in the above formula
MariettaO [177]4 years ago

Answer with explanation:

Product Rule learned by Thomas

 a^3 +b^3=(a+b)(a^2-ab+b^2)

Now we have to find the value of

 (2 x)^3 +1^3\\\\=8x^3+1\\\\=(2 x+1)[(2x)^2-2 \times 2x \times 1 +1^2]\\\\=(2 x+1)[4x^2-4 x +1]

The product that Thomas should choose

 =(2 x+1)(4 x²-4 x+1)

Snowcat [4.5K]

Answer:

C. -0.7

Explanation:

Given the equation:

\frac{1}{2}(-1.4m+0.4)=\boxed{\square}_{}m+0.2​

First, distribute the bracket on the left-hand side:

\begin{gathered} \frac{1}{2}(-1.4m)+\frac{1}{2}(0.4) \\ =-0.7m+0.2 \end{gathered}

The number that makes the given expressions equivalent is -0.7.

The correct choice is C.

Joel earns $1,500 per month. If he spends $375 on rent each month, what percent of his income does he spend on rent?
cricket20 [7]
First, we must express the ratio of rent to Joel's total earning. 375 out of 1500 in its simplest form is 1/4. To express a value in percentage, we must multiply it to 100. Thus, for this case, we have 1/4 x 100 = 25% That means, out of a total of 100%, Joel spends 25%<span>of his income on rent.</span>
