Answer:

–50xy

–40x2

Will not change the Greatest Common Factor.

Step-by-step explanation:

Greatest common factor is the highest factor that divides 2 or more number.

We can find the GCF by multiplying all the factors that are common to each number.

Factors of 36x^(3)=1,2,3,4,6,9,12,18, 36 and x,x^(2),,x^(3)

Factors of 22x^(2)=1,2,11, x and x^(2)

Factors of 144x=1,2,3,4,6,8,9,12,16,18,24,36 and  x and more.

So the common factors to all three numbers are 1,2 and x.

So GCF = 1*2*x=2x

If we use 11 it will change the GCF to 11.

If we use 50xy it will not change the GCF.

If we use 4040x^(2) it will not change the GCF.

IF we use 24 it will change the GCF.

If we use 10y it will change the GCF.
Given:

36x³ - 22x² - 144x

GCF:
36 ÷ 2 = 18
18 ÷ 2 =   9
  9 ÷ 3 =   3  

22 ÷ 2 = 11

144 ÷ 2 = 72
  72 ÷ 2 = 36
  36 ÷ 2 = 18
  18 ÷ 2 =   9
    9 ÷ 3  =  3

2 is the GCF of all terms. We can add 24. It would not change the GCF of the polynomial.

36x³ - 22x² - 144x + 24

A body moving with a velocity of 20 m/s begins to accelerate at 3 m/s2. How far does the body move in 5 seconds?A. 196 m
B. 137.5 m
C. 260 m
D. 162.5 m

Answers

Answer is B. According to the equation of motion s = vt + 1/2 at2 Where s is distance covered, v is velocity, a is acceleration and t is time taken. So, by putting all the values, we get s = (20)(5) + 1/2 (3)(5)2 s = 100 + 1/2 (3)(25) s = 100 + 1/2 75 s = 100 + 37.5 s = 137.5 meters

The 2015 senior class from Puma High School raised funds for an end of the year party at Club Sizzle. If costs $4,000 to rent out Club Sizzle plus $20 per student for food and drinks. If the senior class raised $11,000, how many students can attend the end of year party?

Answers

Answer:

There are 350 students that will be able to go to the party

Step-by-step explanation:

First we must analyze the statement and build a equation based on that, for do that, we will divide the statement a take the information.

1. The 2015 senior class raised funds of $11,000: we will represent this incomes with with a T, so:

T = 11,000

2. The cost to rent out the club sizzle is $4,000 and we will represent this cost with a C, so:

C = 4000

3. The cost per students is $ 20 and we will represent this with a S, then:

S = 20

The question is: how many students can attend, to the party so, we will form the equation:

C + S*X = T

Where X is the number of students that can attend to the party. This equation means that the cost of the club plus 20 dollars per person have to be equal to 11,000.  

Replacing values of T, C and S, we get:

$4,000 + $20*X = $11,000

Now, we will solve for X

20*X = 11000-4000

X = (11000-4000)/20

X = 350

Finally, 350 students will be able to go to the party.

$11,000-$4,000=$7,000
$7,000/$20=350
350 students can attend the end of the year party

Which of the following ordered pairs lies on the graph of h(x) = -2x^2?(1, -4)
(1, -2)
(1, 4)

Answers

given, y= -2x^2;
so, when x=1, y= -2((1)^2)= -2
so pair which lie on graph is (x,y) is (1,-2)
From the function h(x) = -2x^2 or y = -2x^2,
when x = 1, y = -2(1)^2 = -2.

Hence, the answer is (1, -2).

The tree nearest to the classroom is 30 feet tall. In another 10 years it will grow 5 more feet. If the variable h stands for the height of the tree 10 years from now, which of the following choices is the most reasonable value for h?A.
10 feet

B.
3 feet

C.
50 feet

D.
35 feet

Answers

If you would like to know the height of the tree 10 years from now, you can calculate this using the following steps:

h ... the height of the tree 10 years from now
h = 30 feet + 5 feet = 35 feet

The correct result would be D. 35 feet.
