A rectangle has a height of w^2+3w+9w 2 +3w+9w, squared, plus, 3, w, plus, 9 and a width of w^2+2w 2 +2w, squared, plus, 2. Expr
Keith_Richards [23]

Answer:

w⁴+5w³+17w²+24w +18

Step-by-step explanation:

Area of a rectangle = length * width

Given

Length  = w²+3w+9

width = w²+2w+2

Area of the rectangle = (w²+3w+9)(w²+2w+2)

Area of the rectangle = w²(w²) + 2w(w²) + 2w² + 3w(w²) + 3w(2w) + 2(3w)+9w²+9(2w)+9(2)

Area of the rectangle = w^4+2w^3+2w²+3w^3+6w^2+6w+9w²+18w+18

Collect the like terms;

Area of the rectangle = w^4+2w^3+3w^3+2w²+6w²+9w²+6w+18w+18

Area of the rectangle = w⁴+5w³+17w²+24w +18

Hence the area of the entire triangle is w⁴+5w³+17w²+24w +18

What is the simplest form of RootIndex 3 StartRoot 27 a cubed b Superscript 7 Baseline EndRoot?
Vinvika [58]

Answer: 3ab\sqrt[3]{b^4}

Step-by-step explanation:

Given the following expression:

\sqrt[3]{27a^3b^7}

You need to apply the Product of powers property, which states that:

(a^m)(a^n)=a^{(m+n)

Then, you can rewrite the expression as following:

=\sqrt[3]{27a^3b^4b^3}

The next step is to descompose 27 into its prime factors:

27=3*3*3=3^3

Now you must substitute 3^3 inside the given root. Then:

=\sqrt[3]{3^3a^3b^4b^3}

You need to remember that, according to Radicals properties:

\sqrt[n]{a^n}=a^{\frac{n}{n}}=a^1=a

Therefore, the final step is to apply this property in order to finally get the expression is its simplest form. This is:

=3^{\frac{3}{3}}a^{\frac{3}{3}}b^{\frac{4}{3}}b^{\frac{3}{3}}=3ab^{\frac{4}{3}}b=3ab\sqrt[3]{b^4}
