Answer: 27.62

Step-by-step explanation:

plug in 2.3 wherever 'n' is

I'm assuming that the '2' in 8n2 is an exponent

2.3 + 8(2.3)² - 17 =

Using PEMDAS

start out with exponent since there isn't any parenthesis  

(2.3)² = 5.29

2.3 + 8(5.29) - 17

move on to multiplication

8(5.29) = 42.32

2.3 + 42.32 - 17

with addition and subtraction, you do whichever comes first and since this equation starts with addition we'll start there

2.3 + 42.32 = 44.62

then the subtraction

44.62 - 17 = 27.62

Answer:

Step-by-step explanation:

The answer is 27.62

Answer:

A. Slope= -3

B. Slope= -4/3

C. Slope= 11/2

D. Slope= undefined

Step-by-step explanation:

The way I solved it was by graphing the points and then counting the rise/run.

Answer:

4 units

Step-by-step explanation:

The length between point P and Q is from -3 to 1, If you start at -3 and count over the graph to 1 you will get 4 units

Answer: 10

Step-by-step explanation:

b can be 10 as,

7*3 = 21

7+3 = 10

∵ [tex]7x^2[/tex] + 10x + 3

Answer:

[tex]\mbox{\large \; 4\left(3x+5\right)\left(3x+5\right)} = 4(3x + 5)^2}[/tex]

Step-by-step explanation:

We are given the quadratic equation [tex]36x^2+120x\:+\:100[/tex] and asked to factor

Here are the steps

Answer
[tex]\mbox{\large \; 4\left(3x+5\right)\left(3x+5\right)} = 4(3x + 5)^2}[/tex]

Answer: (6x+10)

Step-by-step explanation:

To find the side of the square, we have to first factorise it:

[tex]36x^2[/tex] + 120x + 100

= 36[tex]x^2[/tex] + 60x + 60x + 100

= 12x(3x + 5) + 20(3x + 5)

= (12x+20)(3x+5)

= 4(3x+5)(3x+5)

= 2(3x+5)2(3x+5)

= (6x+10)(6x+10)

∴ Hence, side = (6x+10) units

Step-by-step explanation:

Answer:

A numerical expression contains numbers and operations. An algebraic expression is almost exactly the same except it also contains variables

Answer:

Step-by-step explanation:

Both are similar as they result of both is same. The only difference is their methods of solving them. In numeric expressions, it takes long calculation while in algebraic expressions, we break the expression and then solve it to obtain the result in simpler form.

Answer:

Step-by-step explanation:

[tex]2x^2[/tex] + 13x - 24 to be factorised to find the dimensions:

[tex]2x^2[/tex] + 13x - 24

= [tex]2x^2[/tex] + 16x - 3x - 24

= 2x(x+8) - 3(x+8)

= (2x-3)(x+8)

Length = (2x-3)

Breadth = (x+8)

∴ Increasement in length = 2x - 3 +2 = (2x -1)

Increasement in breadth = x + 8 + 2 = (x+10)

Answer:

Fish A travels faster and by 0.1 meters per second.

Step-by-step explanation:

According to the table, you can see that the seconds are not being measured constantly. To determine the rate of change of meters per second, we can use subtraction on both the numerator and denominator of the expression. Where we divide it into 1 second.

meters/second → 4.8 – 1.6 / 3 – 1 = 3.2 / 2 =

1.6 meters/second.

Now we can compare the rate from fish B by also diving it into 1 second.

3 meters every 2 seconds → 3/2 =

1.5 meters/second.

Since 1.6 > 1.5, Fish A is faster!

And to compare the simplified rates

1.6 – 1.5 = 0.1 meters.

So Fish A is 0.1 meters faster!

1=3392.92

2= 4071.50

3 = 5387.83

4 = 785.40

Using the cosine half angle formula,

[tex]\cos \frac{\theta}{2}=-\sqrt{\frac{1-\frac{1}{9}}{2}}=-\frac{2}{3}[/tex]

Using the sine half angle formula,

[tex]\sin \frac{\theta}{2}=\sqrt{\frac{1+\frac{1}{9}}{2}}=\frac{\sqrt{5}}{3}[/tex]

So, [tex]a_1=-\frac{2}{3}[/tex] and [tex]a_2=\frac{\sqrt{5}}{3}[/tex].

Answer:

1. 16 inches

2. 1256 square feet

Answer: A C and D

Step-by-step explanation:

What I did was look at point A, we see it starts at (-8, 6) this means that if it were to be shifted right 9 and down 4 we would get (1, 2). so, all the answers claiming that the points were shifted right 9 and down 4, or x+9 y-4 are correct.

your answer would be the first option the 3rd and the last option

Step-by-step explanation:

I think you just add them all together

Answer:

Step-by-step explanation:

(27) [tex]7x^2[/tex] + 9x + 2

= [tex]7x^2[/tex] + 7x + 2x + 2

= 7x(x+1) + 2(x+1)

= (7x+2)(x+1)

(29) [tex]8x^2[/tex] - 2x - 1

= [tex]8x^2[/tex] - 4x +2x - 1

= 4x(2x-1) +1(2x-1)

= (4x+1)(2x-1)

(31) [tex]15x^2[/tex] - 16x - 7

= [tex]15x^2[/tex] + 5x - 21x - 7

= 5x(3x + 1) - 7(3x+1)

= (5x-7)(3x+1)

Answer: The correct answer is 34.5

Step-by-step explanation:

1. She did not need to multiply both sides by -7.5

2.  A negative * a negative will make a positive number
