Answer:

x= 44°

Step-by-step explanation:

Solve: f(x) = (x + 1)(x + 1)
Akimi4 [234]

Answer:

f(x) = x² + 2x + 1

Step-by-step explanation:

you know how to multiply 2 expressions ?

let's say in general we have

(a + b)(c + d)

you take one part of one expression and multiply it with all parts of the other expression, then you take the second part of the first expression and multiply it with all parts of the other expression, then a potential third part, then a fourth part and so on, and you add all these things together (well, depending on the actual signs, of course).

so, we get for this simple generic example

a×c + b×c + a×d + b×d

now we use that understanding for our question here.

(x+1)(x+1) = x×x + 1×x + x×1 + 1×1 = x² + x + x + 1 = x² + 2x + 1

Find a 20 given that a 3 = 9 and a 8 = 24
Nimfa-mama [501]

Answer:

<u>a₂₀ = 60</u>

Step-by-step explanation:

<u>Given :-</u>

a₃ = 9

a₈ = 24

<u>To find :-</u>

a₂₀

<u>Solving :-</u>

Expand the given values.

a + 2d = 9 -(1)

a + 7d = 24 -(2)

Now subtract (1) from (2).

=> 5d = 15

=> d = 3

a = 9 - 2d

a = 9 - 6

a = 3

<u>Final answer :-</u>

a₂₀

= a + 19d

= 3 + 19(3)

= 3+ 57

= 60

<u>a₂₀ = 60</u>

Mr. Smith and Mr. Kelly are business partners they agreed to divide the profits in the ratio of 3 to 2 the profit amount of 24,0
nikitadnepr [17]

Answer: Mr. Smith makes 14,400, Mr. Kelly makes 9,600

Step-by-step explanation: First add the ratio together. 3+2=5.

Then divide 24,000 into five parts, 24,000/5 = 4,800.

After getting 4,800, multiply 4,800 by 3 to get Mr. Smith's portion of the money received. 4,800 x 3 = 14,000.

And you can do the same for Mr. Kelly but use 2 instead of a 3.

4,800 x 2 = 9,600

To check your work you can add the two answers together

9,600 + 14,400 = 24,000.

list M and n are the zeros of the polynomial 3x square + 11 x minus 4 then find the value of m divided n plus n dividedm​
Vaselesa [24]

Answer:

Step-by-step explanation:

3x²+11x-4

when splitting the middle term

it becomes

3x²+12x-1x-4

=3x(x+4)-1(x+4)

(3x-1)(x+4)

either 3x-1=0 then x=1/3

or x+4=0 then x= -4

m=1/3

n=-4

therefore

value of m divided n plus n dividedm​=1.25
