Answer: y^2-100.

Step-by-step explanation:

if we have a square with sides 'y' units,

then, its breadth = length = y

If we add 10 to one side it will become (y+10)  (longer one) and subtract 10 from another, then it will become (y-10) (shorter one).

Area of rectangle = breadth x length

So, area of rectangle = (y+10)(y-10)

= y^2-10^2=y^2-100\ \ \ \ \ [(a-b)(a+b)=a^2-b^2]

Hence, the new area as a polynomial = y^2-100.

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}}

Answer:

90\pi

Step-by-step explanation:

The first step is to find the slant height of the cone. Using the pythagorean theorem, you can find that \sqrt{12^2+5^2}=13 cm. Plugging this into the equation, you get \pi \cdot 5 \cdot 13=90\pi. Hope this helps!

Step-by-step explanation:

You do the inverse operation which would be subtraction and multiplication. You add the 6 to the 8 and you get 14. Then you would multiply 14 by 5 to get 70. Hope this helps :D
