Remember
\sqrt{x^2}=x
and
\sqrt[3]{x^3}=x

so
\sqrt{x^2}+\sqrt[3]{y^3}=
x+y



another way is this:
remember that
\sqrt[n]{x^m}=x^\frac{m}{n}
and remember that \sqrt{x}=\sqrt[2]{x}

so
\sqrt{x^2}+\sqrt[3]{y^3}=
x^\frac{2}{2}+y^\frac{3}{3}=
x^1+y^1=
x+y

Answer:

c4+8c3+−3c2+−7c

Step-by-step explanation:

Let's simplify step-by-step.

−3c4−5c2−7c+4c4+8c3+2c2

=−3c4+−5c2+−7c+4c4+8c3+2c2

Combine Like Terms:

=−3c4+−5c2+−7c+4c4+8c3+2c2

=(−3c4+4c4)+(8c3)+(−5c2+2c2)+(−7c)

=c4+8c3+−3c2+−7c

Martha invested a principal amount of $15,000 into a savings account that earns simple interest at a rate of 4.5% per year. How
lidiya [134]

Option A

The simple interest earned over 6 years is $ 4050

<em><u>Solution:</u></em>

Martha invested a principal amount of $15,000 into a savings account that earns simple interest at a rate of 4.5% per year

<em><u>The formula for simple interest is given as:</u></em>

Simple\ Interest = \frac{p \times n \times r}{100}

Where, "p" is the principal and "n" is the number of years and "r" is the rate of interest

From given,

p = 15000

r = 4.5 %

n = 6 years

<em><u>Substituting the values we get,</u></em>

Simple\ Interest = \frac{15000 \times 4.5 \times 6}{100}\\\\Simple\ Interest = 150 \times 4.5 \times 6\\\\Simple\ Interest = 4050

Thus simple interest earned over 6 years is $ 4050

Explain why it can be helpful to use partial quotients when dividing?
Anastasy [175]
In mathematics, a quotient (from Latin: quotiens "how many times", pronounced ˈkwoʊʃənt) is the result of division. For example, when dividing 6 by 3, the quotient is 2, while 6 is called the dividend, and 3 the divisor.

John Sells Hamburgers For $3 Each and cheeseburgers for $3.50 each. One afternoon, he sells a total of 24 burgers for $79. How M
Alexxx [7]
Let the hamburgers be x and cheese burgers be y.

x + y = 24
3x + 3.5 y = 79

x = 24 - y.

Substituting the value of x,

3( 24 - y) + 3.5 y = 79

 72- 3y + 3.5 y = 79
72 + 0.5 y = 79

0.5y = 79 - 72 = 7
1/2 y = 7

thus, y = 7 * 2 = 14

Substituting the value for x,

x + y = 24
x + 14 = 24
x = 24-14 = 10
Thus, x = 10.

Thus, she sold 10 hamburgers and 14 cheeseburgers
