4. See if you can find "like-terms" in the expression and
WITCHER [35]

Answer:

After finding like terms and solving, we get \mathbf{3x^2+3x+16}

Step-by-step explanation:

We need to find like terms and simplify the expression 4- 2x + x^2 + 5x + 12 + 2x^2

Like terms: The terms who have same variable and exponent are called like terms.

So, Combining like terms and solving:

4- 2x + x^2 + 5x + 12 + 2x^2\\=4+12-2x+5x+x^2+2x^2\\Now \ solving:\\=16+3x+3x^2\\Rearranging \ the \ terms:\\=3x^2+3x+16

So, after finding like terms and solving, we get \mathbf{3x^2+3x+16}

<u><em>Note: In the question given we have - and + sign with the term 5x</em></u> i.e 4- 2x + x^2 -+ 5x + 12 + 2x^2

I have solved using +5x, but if the term is -5x then the solution will be:

4- 2x + x^2 - 5x + 12 + 2x^2\\=4+12-2x-5x+x^2+2x^2\\Now \ solving:\\=16-7x+3x^2\\Rearranging \ the \ terms:\\=3x^2-7x+16

So, the answer will be: \mathbf{3x^2-7x+16}

You deposit $200 in an account that pays 5% interest every year. How much money will you have after 6 years? Round to the neares
Nitella [24]

Answer:

\$ 268

Step-by-step explanation:

Compound Interest: If P is initial amount, A is final amount, r is interest rate and n is number of years.

A=P(1+\frac{r}{100})^n

Here\ P=\$ 200,\ r=5\%\ and\ n=6\ years\\\\We\ have\ to\ find\ out\ A\\\\A=200(1+\frac{5}{100})^6\\\\A=200(1+0.05)^6\\\\A=200(1.05)^6\\\\A=200\times  1.340095641\\\\A=268.02\\\\A\approx \$ 268
