Answer:4x^2 +28x +49=(2x +7)^2
Step-by-step explanation:
a2±2ab+b2=(a±b)2
In this case
a=2x and b=7 ...
4x2+28x+49=(2x)2+(2⋅
(2x)⋅
7)+72=(2x+7)2
The expression that represents the length of each side of the square is (2x + 7)(2x + 7)
What is expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given that an expression showing the area of a square, 4x²+28+49,
The length of the side of the square will be the factors of the expression,
Therefore, factorizing, 4x²+28+49,
4x²+28+49
= 4x² + 14x + 14x + 49
= 2x(2x + 7) + 7(2x + 7)
= (2x + 7)(2x + 7)
Hence, the expression that represents the length of each side of the square is (2x + 7)(2x + 7)

Marty can go to one movie on either Friday or Saturday. His choice of movies includes a comedy or an action movie. Which list shows all of the possible outcomes of one movie on one day?
the list of all possible outcomes is: {Comedy on Friday, Action on Friday, Comedy on Saturday, Action on Saturday}
What is possibility?
Possibility refers to the likelihood or chance that something may occur or be true. It is often expressed as a probability or a percentage, which indicates the relative frequency with which an event is expected to happen.
In everyday language, possibility is often used to describe something that could happen or be true, but is not necessarily guaranteed. For example, if there is a 50% chance of rain tomorrow, it is possible that it will rain, but it is not certain.
In mathematics and statistics, possibility is often used in the context of probability theory, which is the branch of mathematics that deals with the study of random events and their probabilities.

Employees at the hardware store are receiving pay raises. Dan’s hourly pay rate is increasing from $12 to $14 and Kathy’s hourly pay rate is increasing from $13 to $15.
What was Dan's percent increase in pay?
What was Kathy's percent increase in pay?
Answer:
12/14 x 100% = 85.7%
100% - 85.7% = 14.3% increase for Dan
13/15 x 100% = 86.7%
100% - 86.7% = 13.3% increase for Kathy

f(x) = -3x- 6 and g(x) = -4x + 9, find g(g(y))
9514 1404 393
Answer:
g(g(y)) = 16y -27
Step-by-step explanation:
Simplify from the inside out, as the order of operations tells you.
g(g(y)) = g(-4y +9) = -4(-4y +9) +9
g(g(y)) = 16y -36 +9
g(g(y)) = 16y -27

justine and her cousin natalie are picking out snacks at the corner store for movie night. natalie spends $5.30. justine spends 1 1/3 times as much as natalie. how much money do the girls spend in all?
Answer:
$12.35
Step-by-step explanation:
to figure out how much justine spends we need to multiply 1 1/3 with 5.30
1 1/3=4/3
4/3=1.33(decimal for easy calculations)
1.33*5.30=7.05
so now to figure out how much BOTH the girls spend:
7.05+5.30=12.35
