The approximate length of the diagonal of the rectangle IS 7.21 unit , Option D is the correct answer.

<h3>What is a Rectangle ?</h3>

A rectangle is a polygon with four sides and opposite sides parallel and equal , all the angles measure to 90 degree.

The diagonal of a rectangle divides it into two right angled triangle

The length of the rectangle is 6 units

The breadth of the rectangle is 4 units

The diagonal length will be equal to the hypotenuse of the triangle of side 4 and 6 units

By Pythagoras theorem

the length of the diagonal =

\rm \sqrt{ 6^2 + 4^2}\\\\\sqrt{36+16}\\\\\sqrt {52}

7.21 unit

The approximate length of the diagonal of the rectangle IS 7.21 unit , Option D is the correct answer.

How do you solve a/7+5/7=2/7
Anton [14]
\frac{a}{7} + \frac{5}{7} = \frac{2}{7} \\ \frac{a + 5}{7} = \frac{2}{7} \\ 7(\frac{a + 5}{7}) = 7(\frac{2}{7})
a + 5 = 2
a + 5 - 5 = 2 - 5
a = -3

Hope this helps! :)

Simplify (4x^2-7x+14)(3x+5x^2-6)<br> Please show work
tatiyna

Answer:

-23x^3+20x^4+25x^2+84x-84

Step-by-step explanation:

1 Expand by distributing sum groups.

4x^2(3x+5x^2-6)-7x(3x+5x^2-6)+14(3x+5x^2-6)

2 Expand by distributing terms.

12x^3+20x^4-24x^2-7x(3x+5x^2-6)+14(3x+5x^2-6)

3 Expand by distributing terms.

12x^3+20x^4-24x^2-(21x^2+35x^3-42x)+14(3x+5x^2-6)

4 Expand by distributing terms.

12x^3+20x^4-24x^2-(21x^2+35x^3-42x)+42x+70x^2-84

5 Remove parentheses.

12x^3+20x^4-24x^2-21x^2-35x^3+42x+42x+70x^2-84

6 Collect like terms.

(12x^3-35x^3)+20x^4+(-24x^2-21x^2+70x^2)+(42x+42x)-84

7 Simplify.

-23x^3+20x^4+25x^2+84x-84
