Factor a GCF from the expression, if possible.
Factor a Trinomial, if possible.
Factor a Difference Between Two Squares as many times as possible.
If the equation is in the form a2-b2, factor it to (a+b)(a-b). Equations with two variables factor differently than basic quadratics. For any equation a2-b2 where a and b do not equal 0, the equation factors to (a+b)(a-b). For example, the equation 9x2 - 4y2 = (3x + 2y)(3x - 2y).

At a bowling alley, there is a flat fee of
$
5.00
to rent shoes. In addition, it costs
$
1.25
for each game bowled.
Which equation shows the total cost (
c
) for the number of games (
g
) one bowls?
Answers
Answer:
I don't see any answer options, but the total cost should be:
c = $5.00 + $1.25g
Step-by-step explanation:
Assuming that the cost is for one person playing g games, and that person needs to rent 1 pair of shoes, the cost should be:
c = $5.00 + $1.25g

A diner has collected data about customer coffee-drinking habits. They have calculated that P(cream) = 0. 5, P(sugar) = 0. 6, and P(cream or sugar) = 0. 7. Determine the P(cream and sugar). 0. 4 0. 5 0. 6 0. 7.
Answers
Probability of an event is the measure of its chance of occurrence. The value of the probability P(cream and sugar) is given by: Option A: 0.4
What is the addition rule of probability for two events?For two events A and B, we have:
Probability that event A or B occurs = Probability that event A occurs + Probability that event B occurs - Probability that both the event A and B occur simultaneously.
This can be written symbolically as:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
For the considered case, the probabilities are:
P(cream) = 0. 5P(sugar) = 0. 6P(cream or sugar) = 0. 7Thus, we get;
P(cream or sugar) = P(cream) + P(sugar) - P(cream and sugar)
0.7 = 0.5 + 0.6 - P(cream and sugar)
P(cream and sugar) = 1.1 -0.7 = 0.4
Thus, the value of the probability P(cream and sugar) is given by: Option A: 0.4

If X = 6 cm and Z = 10 cm, what is the length of Y?
A. 8 cm
B. 8 cm
C. 10 cm
D. 6 cm
Answers
Answer:
If XYZ is a triangle, then Y = 8 cm
Step-by-step explanation:
X^2 + Y^2 = Z^2, by the Pythagorean Theorem.
Z, in this equation, represents the hypotenuse; the hypotenuse must be the longest side, and we can therefore eliminate C, 10 cm, without even beginning. Then, we may plug the given values in.
(6)^2 + Y^2 = 10^2
36 + Y^2 = 100
Y^2 = (100 - 36) = 64
Y = 8 cm

2 2240
3 3360
4 4480
A. The rate of change is constant and represents a speed of 1120 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.
B. The rate of change is constant and represents a speed of 3360 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.
C. The rate of change is constant and represents a speed of 2240 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.
D. The rate of change is constant and represents a speed of 4480 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.
Answers
From the relationship between the distance and time, the rate of change is constant and represents a speed of 1120 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.
What is a linear equation?A linear equation is in the form:
y = mx + b
Where y,x are variables, m is the rate of change and b is the initial value of y.
Let y represent the distance travelled by the bike after x minutes.
From the table:
Rate of change = (4480 - 1120) / (4 - 1) = 1120 ft/min
The rate of change is constant and represents a speed of 1120 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.

A project manager must select four analysts from her group to write four
different software functions. There are 5 junior and 8 senior analysts in her group.
The first and fourth functions can be written by any of the analysts. The second
function must be written by a senior person and the third function must be written
by a junior person. How many ways are there for her to assign the analysts to the
functions if no person can be assigned to more than one function?
Answers
Using the Fundamental Counting Theorem, it is found that there are 4,440 ways to assign the analysts.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
In this problem:
With the first function being written by a senior, we have that: [tex]n_1 = 8, n_2 = 7, n_3 = 5, n_4 = 10[/tex].With the first function being written by a junior, we have that: [tex]n_1 = 5, n_2 = 8, n_3 = 4, n_4 = 10[/tex].Hence:
N = (8 x 7 x 5 x 10) + (5 x 8 x 4 x 10) = 4400.
There are 4,440 ways to assign the analysts.

PLEASE HELP ME OUT!!!!
Answers
Answer:
Marcia is not correct.
See explanation below.
Step-by-step explanation:
The terms are
2x²
4xy
8xy^4
The terms broken down into products of prime factors are:
2x² = 2 × x × x
4xy = 2 × 2 × x × y
8xy^4 = 2 × 2 × 2 × x × y × y × y × y
To find the GCF, we circle the common factors of the three terms (here we use bold type instead of circling.)
2x² = 2 × x × x
4xy = 2 × 2 × x × y
8xy^4 = 2 × 2 × 2 × x × y × y × y × y
The GCF is the products of the circled (bold) factors.
GCF = 2x
Marcia's answer is the Least Common Multiple.
For the LCM, you use all factors that are common and not common with the larger exponent.
LCM = 2 × 2 × 2 × x × x × y × y × y × y = 8x²y^4
Marcia's mistake is that she calculated the LCM instead of the GCF.
Answer:
Marcia is not correct.
The explanation is above.
Answer:
See below.
Step-by-step explanation:
2x^2, 4xy, and 8xy^4
She is incorrect.
The GCF is 2x.
