Answer:

4x^2+3x-6

Step-by-step explanation:

instructions included above :)

Answer:

200+10+6=216

Step-by-step explanation:

2 hundred and 16 is in word form

Since 200 can be written as a sum of 2 100's, hence there are two hundred in the expression given,

Given the expression 200 + 10 + 6

Each term can be written in words as shown:

200 is two hundred

200 = 100 + 100

Since 200 can be written as a sum of 2 100's, hence there two hundred in the expression given,

Answer: D

Step-by-step explanation:

<3

Answer:

The correct answer is d. Combine the like terms on the left side of the equation.

Answer:

Step-by-step explanation:

f(x) = x - 14

To find f(2) substitute the value of x that's 2 into f(x). That is for every x in f(x) replace it with 2

We have

f(2) = 2 - 14

We have the final answer as

Hope this helps you

Here, we are given with a polynomial f(x)

[tex]f(x) = x - 14[/tex]

And we are asked to find f(2).....?

We can see that, 2 is in place of x. So for finding its value, we need to substitute 2 in place of x.

Substituting 2 in place of x:

[tex]f(x) = x - 14[/tex]

[tex]f(2) = 2 - 14[/tex]

Solving further,

[tex]f(2) = \boxed{- 12}[/tex]

And, we're done with the value of f(2)

Answer:

$200.

Step-by-step explanation:

Each computer costed $1,250.

Mr. Chan bought 20 computers.

20 × $1,250 = $25,000

$25,000 out of the $30,000 was spent on computers. That leaves $5,000. Which means $5,000 was spent on the printers.

$5,000 ÷ 25 = $200

(25 = amount of printers.)

So each printer was $200.

Answer:

In a. hypotenuse is AC

In b. hypotenuse is EF

In c. hypotenuse is HG

2.

a. is right triangle

b. is not right triangle

c. is right triangle

Step-by-step explanation:

in first question we have to find the hypotenuse and hypotenuse is always the side opposite to 90 degree angle

in second question we have to square each of the sides if sum of two squared side equal to the third one that triangle is right angle triangle

Answer:

3,400 people

Step-by-step explanation:

First, find how many minutes are between noon and 1:30 pm

This is an hour and 30 minutes, so it will be 90 minutes

Then, multiply 90 by 35, since 35 people enter per minute

90(35)

= 3150

Then, add the 250 people that were already in it

3150 + 250

= 3400

So, there will be 3,400 people in the stadium

Answer:

3400

Step-by-step explanation:

Answer:

b= 3

d= 10/7

Step-by-step explanation:

Basically what you do is 12/6 and 10/7 for d, because it is the greatest and least on both sides. You do the same for b so it would be 10-7=3 and 12-6=6

Answer:

y=5

Step-by-step explanation:

all you have to do is divide 6 on both sides

to get 5 cause negatives cancel

y = 5

Step-by-step explanation:

[tex] - 30 = - 6y[/tex]

Divide both sides of the equation by -6

[tex] \frac{ - 30}{ - 6} = \frac{ - 30}{ - 6} \\ \\ y = 5[/tex]

Answer:

We have the relation:

1ft = 12 inches.

Then, if we cube both sides, we have:

(1ft)^3 = (12 in)^3

1ft^3 = 288 in^3.

Now we know that:

The bucket is 864 in^3

The tank is 7 ft^3.

knowing that 1 ft^3 = 288in^3

Then 7 ft^3 is seven times that:

7ft^3 = 7*(1ft^3) = 7*(288in^3) = 2016 in^3

Now the number of buckets needed to completely fill the tank is:

N = (2016 in^3)/(864in^3) = 2.33

So you need 2.33 buckets, or we can round it up to 3 buckets, where the third bucket will have some water inside it when the tank is completely filled.

Answer:

7.1 cm

Step-by-step explanation:

The diagonal of a cube connects two opposite corners.

You can use the diagonal of a cube in a right triangle in which it is the hypotenuse. The legs of the triangle are a diagonal of a face and an edge.

Let the length of the edge be s.

a^2 + b^2 = c^2

[tex] s^2 + 10^2 = (\sqrt{150})^2 [/tex]

[tex] s^2 + 100 = 150 [/tex]

[tex] s^2 = 50 [/tex]

[tex] s = \sqrt{50} [/tex]

[tex] s = 5\sqrt{2} [/tex]

s = 7.1

Answer: 7.1 cm

Step-by-step explanation:

the absolute value is the numbers UNIT DISTANCE from the origin (0,0). since you can't have negative distance, the result is always positive. Can be solved by counting distance on a graph Not by the actual numbers on the line (-1,-2,-3, etc) but by counting the "boxes" from a point to the origin. hope this makes sense!

Answer:

the absolute value of negative number makes it a positive number

Answer:

r = 0

Step-by-step explanation:

First, combine like terms:

(-2r - 4r) = 0

(-6r) = 0

Isolate the variable, r. Divide - 6 from both sides:

(-6r)/-6 = (0)/-6

r = 0/-6 = 0

r = 0 is your answer.
