The length of a rectangle is (3 + √7)m and its width is (1 + 2√7)n. What is the
Andru [333]

Answer:

A=(17+7\sqrt7)\ m^2

Step-by-step explanation:

Given that,

The length of the rectangle, l=(3+\sqrt7)\ m

The width of the rectangle, b=(1+2\sqrt{7} )\ m

We need to find the area of the rectangle. We know that the area of the rectangle is given by :

A=l\times b

Put all the values in the above formula.

A=(3+\sqrt7)\times (1+2\sqrt7)\\\\=3+3\times 2\sqrt7 +\sqrt7+2(\sqrt7)^2\\\\=3+6\sqrt7+\sqrt7+14\\\\=(17+7\sqrt7)\ m^2

So, the area of the rectangle is (17+7\sqrt7)\ m^2.

T^3(8 + 9t) - (t2 + 4) (2 – 3t)
mezya [45]

Answer: a & b

<u>Step-by-step explanation:</u>

    t³(8 + 9t) - (t² + 4)(2 - 3t)

=   8t³ + 9t⁴ - (2t² - 3t³ + 8 - 12t)

=   8t³ + 9t⁴ - 2t² + 3t³ - 8 + 12t

=   9t⁴ + 11t³ - 2t² + 12t - 8

a) The simplified expression is a polynomial.  TRUE

b) The simplified expression has a constant term.  TRUE

c) The simplified expression is cubic.  False - it is degree 4
