DIA [1.3K]3 years ago
8 0

Step-by-step explanation:

{(9p - 5q)}^{2}

Hence according to ,

{(a - b)}^{2}  =  {a}^{2}   -  2ab +  {b}^{2}

So,

{(9p)}^{2}  - 2 \times 9p \times 5q +  {(5q)}^{2}

81 {p}^{2}  - 90pq + 25 {q}^{2} (ans)

Perform the indicated operation to write given polynomial in standard form: (2x^3 − 6x^2 − 7x − 2) +(x^3 +x^2 +6x − 12)
Kipish [7]

Answer:

\left(2x^3-6x^2-7x-2\right)+\left(x^3+x^2+6x-12\right)=3x^3-5x^2-x-14

Step-by-step explanation:

To add the polynomials

Remove parentheses:

\left(2x^3-6x^2-7x-2\right)+\left(x^3+x^2+6x-12\right)=2x^3-6x^2-7x-2+x^3+x^2+6x-12

Group like terms:

=2x^3+x^3-6x^2+x^2-7x+6x-2-12

Add similar elements:

=3x^3-6x^2+x^2-7x+6x-2-12\\=3x^3-5x^2-7x+6x-2-12\\=3x^3-5x^2-x-2-12\\=3x^3-5x^2-x-14

The Standard Form for writing down a polynomial is to put the terms with the highest degree first,its term of 2nd highest is 2nd etc..

In our case the standard form is  

\left(2x^3-6x^2-7x-2\right)+\left(x^3+x^2+6x-12\right)=3x^3-5x^2-x-14

What is the surface area of the pyramid?
Leviafan [203]

Answer:

40

Step-by-step explanation:

Find the area of each side and add them together. The area of triangles equals Height time 1/2base so you get a=1/2(4)(3). A=6. 6+6+6+6=24 plus the base which is 4x4=16. 26+16=40

40 is our final answer

Solve the inequality. Then graph the solutions on a number line.
Lubov Fominskaja [6]

Answer:

x < 4

Step-by-step explanation:

Given the inequality :

- 20 > - 4(2x - 3)

Open the bracket

-20 > - 8x + 12

Collect like terms

-20 - 12 > - 8x

-32 > - 8x

Divide both sides by - 8

4 > x

x < 4
