Answer:

The equivalent expression can be -5r+5 or 5(-r+1).

Step-by-step explanation:

Consider the provided expression.

-5+(-5r)+10

Open the parentheses as shown.

-5-5r+10

Arrange the like terms together as shown.

-5r-5+10

Now subtract the like terms as shown.

-5r+5

Or

5(-r+1)

Thus, the equivalent expression can be -5r+5 or 5(-r+1).

Answer is R+10
you have to distribute the + into -5 which will still be -5r and you keep the 10

Find the missing term<br> (a^4+9a^3-10a^2)+(8a^4+__+a)=9a^4+15a^3-10a^2=a
Arte-miy333 [17]

Answer:

6a³

Step-by-step explanation:

a⁴ + 9a³ - 10a² + 8a⁴ + X + a = 9a⁴ + 15a³ - 10a² = a

9a⁴ + 9a³ - 10a² + X + a =  9a⁴ + 15a³ - 10a² = a

9a³ + X + a = 15a³  = a

6a³ = X

checking: a⁴+ 8a⁴ + 6a³  =  15a³

9a⁴= 9a³

= a

What are the potential zeros of f(x)=6x^4+ 2x^3 - 4x^2 +2?
Dmitry_Shevchenko [17]

The potential zeros of f(x)=6x^4+ 2x^3 - 4x^2 +2 are ±(1, 1/2, 1/3, 1/6, 2, 2/3)

<h3>How to determine the potential zeros of the function f(x)?</h3>

The function is given as:

f(x)=6x^4+ 2x^3 - 4x^2 +2

For a function P(x) such that

P(x) = ax^n +...... + b

The rational roots of the function p(x) are

Rational roots = ± Possible factors of b/Possible factors of a

In the function f(x), we have:

a = 6

b = 2

The factors of 6 and 2 are

a = 1, 2, 3 and 6

b = 1 and 2

So, we have:

Rational roots = ±(1, 2)/(1, 2, 3, 6)

Split the expression

Rational roots = ±1/(1, 2, 3, 6)/ and ±2/(1, 2, 3, 6)

Evaluate the quotient

Rational roots = ±(1, 1/2, 1/3, 1/6, 2, 1, 2/3, 1/3)

Remove the repetition

Rational roots = ±(1, 1/2, 1/3, 1/6, 2, 2/3)

Hence, the potential zeros of f(x)=6x^4+ 2x^3 - 4x^2 +2 are ±(1, 1/2, 1/3, 1/6, 2, 2/3)

The complete parameters are:

The function is given as:

f(x) = 3x^3 + 2x^2 + 3x + 6

The potential zeros of f(x)=6x^4+ 2x^3 - 4x^2 +2 are ±(1, 1/2, 1/3, 1/6, 2, 2/3)

PLEASE HELP ME !ASAP!!
podryga [215]

Solution :

First term, a₀ = -10 .

Common difference of A.P. , d = -8 - (-10) = 2 .

Last term, aₙ = 24 .

We know, last term is given by :

aₙ = a₀ + (n-1)d

24 = -10 + (n-1)×2

2n - 2 = 34

n = 18

Now, sum of series is given by :

S_n = \dfrac{n}{2} \times ( 2a+(n-1)d)\\\\S_n = \dfrac{18}{2} \times ( 2\times -10 + ( 18 -1) \times 2)\\\\S_n =  126

Hence, this is the required solution.

You paint a border around the top of the walls in your room. What angle does X repeat the pattern? 154
Grace [21]

What does 154 mean in your question?

I assume your room is a square. If so, each corner of the room has a 90 degree angle for a total of 360 degrees.

The angle that is repeated, I assumed based on your obscure question, is 90 degrees.

So, x = 90 degrees.
