A.) To find the perimeter, add two lengths and two widths.
length= 3x+7
width= 2x-3
3x+7+3x+7+2x-3+2x-3
Combine like terms
you end up with an expression like this:
14x+8 cm

B.) Plug in 4 for x into the new expression:
14(4)+8
perimeter=64 cm

C.)When multiplying polynomials, it's just like normal multiplication, except remember to add the exponents.
3x*2x=6x^2
7*-3= -21
So, the new expression is:
6x^2-21 cm squared
D.) Again, plug in the 4 for x.
6(4^2)-21
4*4=16
16*6=96
96-21=75
Area=75 cm squared
E.) If the length is 5 cm longer:
Remember, the length is 3x+7
So, just add 5 to the expression.
7+5=12
The new expression is:
3x+12
Then, add that like you did before.
3x+12+3x+12+2x-3+2x-3
New expression:
Perimeter=10x+18 cm

Answer:

40%

Step-by-step explanation:

Her monthly paycheck was 120 dollars, because thats how much she earned that month. If she saved 48 dollars, then the percentage of the paycheck she saved is the percent of 120 that is 48 dollars, or 48/120. Simplifying, we have 2/5, (because you can divide both the top and the bottom by 24), and 2/5 is equal to 40%

N is a rational number.m is an irrational number.n2 cannot be an irrational number? why or why not
Korolek [52]

If n is rational, it means that

n\in\mathbb{Q}\Rightarrow n=\frac{p}{q},\quad p\in\mathbb{Z},\quad q\in\mathbb{Z}^*

Therefore when we do n² we can write it as

n^2=\frac{p^2}{q^2},\quad p\in\mathbb{Z},\quad q\in\mathbb{Z}^*

Remember that the product of two integer numbers is also an integer, therefore we can guarantee that

p^2\in\mathbb{Z}\text{ and }q^2\in\mathbb{Z}^*

Then we can confirm that n² is the quotient of two integers and the denominator is not zero, therefore, n² is always rational, it cannot be an irrational number

What is the answer to (6+4)tothe3power-1tothe8power
Ipatiy [6.2K]

Hey there!

\huge\boxed{(6 + 4)^3 - 1^8}

\huge\boxed{= 10^3 - 1^8}

\huge\boxed{10^3}

\huge\boxed{= 10\times10\times10}

\huge\boxed{= 100\times10 }

\huge\boxed{= 1,000}

\huge\boxed{1^{8}}

\huge\boxed{= 1\times1\times1 \times 1 \times 1 \times 1 \times 1 \times 1}

\huge\boxed{= 1 \times 1 \times 1 \times 1}

\huge\boxed{= 1\times1}

\huge\boxed{= 1}

\huge\boxed{1,000 - 1}

\huge\boxed{= 999}

\huge\text{Answer: \textsf{999}}

\huge\text{Good luck on your assignment \& enjoy your day!}
