Please help me and include step by step!!!<br> (x+9)(x-9) Polynomial identities
WITCHER [35]

Answer:

The given expression is simplified as (x + 9)(x -9)  = x^{2}   - 81

Step-by-step explanation:

Here,the given expression is (x+9)(x -9)

Using the ALGEBRAIC IDENTITY:

(a +b)(a -b)  = a^2  - b^2

Now, here in the given expression (x + 9)(x -9)

Comparing it the left side of the identity,

we get  a  =  x

    and  b = 9

The right side of the equation is a^{2}   - b^{2}

Substituting the value of a and b, we get

⇒ (x + 9)(x -9)  =   (x)^{2}   - (9)^{2}

= x^{2}   - 81

Hence, the given expression is simplified as (x + 9)(x -9)  = x^{2}   - 81

Write the expression 5x+4x^2(2x+7)-6x^2-9x as a polynomial in standard form
Sever21 [200]
5x + 4x²(2x + 7) - 6x² - 9x
5x + 8x³ + 28x² - 6x² - 9x

8x³ + 22x² - 4x

This can be simplified to:

2x(4x² + 11x - 2)

I don't know which of those answers you are looking for.

PLEASE HELPPPPPP!!!!!!Solve this system of linear equations separate the x-and y-values with a comma
GenaCL600 [577]

Answer:

x=-6,\\y=6

Step-by-step explanation:

Rewrite the system of equations as:

\begin{cases}-13x+2y=90\\-6x+2y=48\end{cases}

Subtract the second equation from the first to isolate x:

-13x+2y-(-6x+2y)=42,\\-7x=42, \\\fbox{$x=-6$}

Plug in x=-6 into any of the equations above and solve for y:

-6(-6)+2y=48,\\2y=12,\\\fbox{$y=6$}

Verify that the solution pair (-6, 6) works \checkmark

Therefore, the solution to this system of equations is:

x=-6,\\y=6

Vanessa has 6 dimes and 2 pennies. Joachim has i dollar,3 dimes,and 5 pennies. Jimmy has 5 dollars and 7 pennies.They want to pu
Shalnov [3]

Answer:

Step-by-step explanation:

The worth of a dime is 10 cents. Converting to dollars, it becomes

10/100 = $0.1

The worth of a penny is 1 cent. Converting to dollars, it becomes

1/100 = $0.01

Vanessa has 6 dimes and 2 pennies. The total amount of money that she has is

(6 × 0.1) + (2 × 0.01)

= 0.6 + 0.02 = $0.62

Joachim has 1 dollar,3 dimes,and 5 pennies. The total amount of money that she has is

1 + (3 × 0.1) + (5 × 0.01)

= 1 + 0.3 + 0.05 = $1.35

Jimmy has 5 dollars and 7 pennies. The total amount of money that he has is

5 + (7 × 0.01)

= 5 + 0.07 = $5.07

The total amount of money that they have is

0.62 + 1.35 + 5.07 = $7.04

Since the game costs $8, then they don't have enough money. The additional amount of money that they need is

8 - 7.04 = $0.96
