What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To determine which of the options is a factor of x² + 8x - 48,
We can use either factoring or the quadratic formula.
First, let's try factoring:
x² + 8x - 48 = 0
We need to find two numbers that multiply to -48 and add to 8.
One possible pair of numbers is 12 and -4:
(x + 12)(x - 4) = 0
Now we can see that x = -12 or x = 4 are the solutions to the equation. None of the options given match these solutions.
Therefore,
The factors of the expression are:
(x + 12) and (x - 4).

Lupe had $100 to buy party supplies for her little sister's birthday. She bought 12 bags of party favors and 15 party hats. Each bag of party favors cost $5.30, and each party hat cost $1.95. How much money did Lupe have left after her purchases? $7.15 $20.50 $36.40 $65.75
Answers
Answer:
He had 7.15 dollars left over
Step-by-step explanation:
12 x 5.3 = 63.6
15 x 1.95 = 29.25
63.6 + 29.25 = 92.85
100 - 92.85 = 7.15
hope this helps you :)
pls mark brainlest ;)
The money left with Lupe after her purchase is $7.15.
Given,
Lupe had $100 to buy party supplies for her little sister's birthday.
She bought 12 bags of party favors and 15 party hats.
Each bag of party favors costs $5.30.
Each party hat cost $1.95.
We need to find how much money Lupe has left after her purchases.
How do we find the amount left after spending from the total amount?We will subtract the amount spent from the total amount given.
The number of spending may depend on the number of items bought and the cost of each item.
If one item cost = $a
And number of items bought = 2
The total amount spent = 2 x $a = $2a
Find the amount Lupe has.
= $100
Find the cost of one party bag.
= $5.30
Find the cost of one party hat.
= $1.95
Find the number of the party bags.
= 12
Find the number of the party hats.
= 15
Find the cost of 12 party bags.
= 12 x $5.30
= $63.6
Find the cost of 15 party hats.
= 15 x $1.95
= $29.25
Find the money left.
= $100 - ($63.6 + $29.25)
= $100 - $92.85
= $7.15
Thus the money left with Lupe after her purchase is $7.15.

Given :
Miki has 104 nickels and 88 dimes.
She wants to divide her coins into groups where each group has the same number of nickels and the same number of dimes.
To Find :
Largest number of groups she can have .
Solution :
In the given question we need to find the largest number of groups she can have i.e we have to find the LCM of 104 and 88 .
Now , factorizing both of them , we get :
[tex]104=1\times 2\times 2\times 2\times 13[/tex]
[tex]88=1\times 2\times 2\times 2\times 11[/tex]
Form above , we can say that common factors are :

What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given expression is 14x - 2. The value of x is 7. The value of the expression at x =7 will be calculated as:-
E = 14x - 2
E = 14 x 7 - 2
E = 96

Linda just turned 15 and is planning to go to college. She has researched her favorite Texas university and discovered the tuition there is around $14,000 per year. From her 15th birthday, Linda received a $5000 gift that she will use for her first year of college tuition. Linda will begin her new part time job soon and wants to save money every month for the next 3 years to also contribute to her first year of college. What is the minimum amount of money Linda needs to save in order to completely pay for her first year of college tuition?
Answers
Answer:
Linda needs to raise a minimum of $9,000 to completely pay for her tuition fee for the first year, that is, $250 per month
Step-by-step explanation:
Tuition fee = $14,000 per year
Linda received a $5000 gift that she will use for her first year of college tuition during her 15th birthday
Amount remaining = Tuition fee - gift money received
= $14,000 - $5,000
= $9,000
Linda needs to raise $9,000 in the next three years to contribute to her first year of college tuition
The minimum amount Linda needs to save each month in the next three years to raise $9,000
= Remaining tuition / 3 years
= $9,000 / 3 * 12 months
= $9,000 / 36 months
= $250 per month
