Answer:

8 = x

or

x = 8

Step-by-step explanation:

x – 3 = 5

x + -3 + 3 = 5 + 3

x = 5 + 3

(5 + 3 = 8)

x = 8

Answer:

x=8

Step-by-step explanation:

x-3=5

x-3+3=5+3

x=8

Answer:

x-1

Step-by-step explanation:

Area= x^2+4x-5

Width= x+5

Area= Length*breadth

x^2+4x-5=length*x+5

Length=x^2+4x-5/x+5

Therefore, length= x-1

Answer:

x-1

Answer:

-1 < -0.25

Step-by-step explanation:

-1 is less than -0.25

less than symbol = <

greater than symbol = >

Example; -1 > -2 --- negative one is greater than negative two OR -2 < -1 --- negative two is less than negative one

Answer:

-1<-0.25

Step-by-step explanation:

Answer: A

Step-by-step explanation: As it is a data set that has been equally represented, it is ok to predict.

Answer:

10 miles

35/7 is 5 so therefore if you do 5+5+5+5+5+5+5 is 35

so that means 2 gallons which is 10

Answer:

If it were like that, 9/20 would be baseball card. 9/20 = X/60

x=27 since 20x3=60

Answer:

short base: 6 yards

long base: 8 yards

Step-by-step explanation:

Our understanding of your figure is shown below.

The question says the "shortest side" and the "width" have the same dimension. If the "width" is a reference to "height 6 yards", then it seems the "shortest side" is 6 yards. Since the slant sides are longer than the height, the "shortest side" is also the "short base."

The short base is 6 yards.

__

The long base overhangs the short base by 1 yard on either end, so it is a total of 2 yards longer than the short base. It it 6+2 = 8 yards long.

The long base is 8 yards.

Hope this is correct, if not then feel free to let me know. I'm sorry in advance if it is incorrect.

Answer:

The graph has pages on the X-axis and price (dollars) on the Y-axis

Step-by-step explanation:

The X-axis will always have the independent variable (pages), while the Y-axis will have the dependent variable (number of pages).  The pages will exist no matter how many there are, but the price is influenced by the number of pages.

Answer:

m = .451

Step-by-step explanation:

3.3 + 10m = 7.81

Subtract 3.3 from each side

3.3-3.3 + 10m = 7.81-3.3

10 m =4.51

Divide each side by 10

10m/10 = 4.51/10

m = .451

Answer:

0.451

Step-by-step explanation:

3.3+10m=7.81

10m = 7.81-3.3

10m = 4.51

m = 4.51/10

m = 0.451

Answer:

the standard form is 63029

Answer:

25.12

Step-by-step explanation:

the formula of a cone is pi r^2 * h/3

r = radius and h = height

the radius is 2 and the height is 3

and the question says use 3.14 instead of pi so

we have

3.14 * 2^2 * 6/3

2*2 or 2^2 = 4

3.14 * 4 * 6/3

6/3 = 2

3.14 * 4 * 2

4*2 = 8

and 8 * 3.14 is 25.12

Answer:

16b^4-9

Step-by-step explanation:

Factoring gives us 16b^4+12b^2-12^2-9. Simplifying gives us the answer which is 16b^4-9

Answer:

[tex]16b^4-9[/tex]

Step-by-step explanation:

When multiplying binomials, we can use a method called FOIL (First-Outside-Inside-Last).

For [tex](t_1+t_2)(t_3+t_4)[/tex], let:

[tex]t_1\implies \text{First Term},\\t_2\implies \text{Second Term},\\t_3\implies \text{Third Term},\\t_4\implies \text{Fourth Term}[/tex]

In the FOIL method, the steps go:

[tex]\text{\textbf{F}irst: Multiply the first and third terms (first term of each binomial)},\\\text{\textbf{O}utside: Multiply the first and fourth terms},\\\text{\textbf{I}nside: Multiply the second and third terms},\\\text{\textbf{L}ast: Multiply the second and fourth terms (last term of each binomial) }[/tex]

Given [tex](4b^2+3)(4b^2-3)[/tex], we have:

[tex]\text{First: }4b^2\cdot 4b^2,\\\text{Outside: }4b^2\cdot -3,\\\text{Inside: }3\cdot 4b^2,\\\text{Last: }3\cdot -3,\\\rightarrow 16b^4-12b^2+12b^2-9[/tex]

Combine like terms:

[tex]\boxed{16b^4-9}[/tex]
