Standard Form: ax² + bx + c = 0Expand by FOIL-ing (First, Outside, Inside, Last)Step-by-step explanation:
Step 1: Define
(x - 5)²
Step 2: Expand
Rewrite: (x - 5)(x - 5)Expand [FOIL]: x² - 5x - 5x + 25Combine like terms: x² - 10x + 25Answer: x^2 -10x + 25
Step-by-step explanation:
First example the expression.
(x -5)(x-5) Now find the product
(x -5)(x-5) = x^2 -5x -5x + 25
x^2 - 5x - 5x + 25 Now combine like terms to break it down.
x^2 -10x + 25

A man bought a calf for $200 and sold it for
$250. What was his gain as a percentage of the
cost price?
Answer:
Step-by-step explanation:
250 is 125% of 200
So,
He gained 25% in profit
Based on the information given his gain as a percentage of the cost price is 25%.
Using this formula
Cost price percentage=Selling price-Cost price/Cost price
Where:
Selling price=$250
Cost price=$200
Let plug in the formula
Cost price percentage=$250-$200/$200
Cost price percentage=$50/200
Cost price percentage=0.25×100
Cost price percentage=25%
Inconclusion his gain as a percentage of the cost price is 25%.

What is the difference between an equation and an inequality?
a - an equation includes numbers, but an inequality doesn't
b- an inequality includes numbers, but an equation doesn't
c- an equation includes an equal sign, but an inequality doesn't
d- an inequality includes an equal sign, but an equation doesn't
Answer:
The correct answer should be C. Hope I helped.
Answer:
C - an equation includes an equal sign, but an inequality doesn't
Step-by-step explanation:
Although both equations and inequalities are ways to show how expressions relate to one another, an equation is the relationship between expressions with an equals sign ( [tex]=[/tex] ) between them, however, an inequality is a way to express two or more expressions with [tex]<[/tex], [tex]\leq[/tex], [tex]>[/tex] or [tex]\geq[/tex] between them. They both include numbers, so the correct option is C.
Hope this helps :)

Algebra I
Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
x - y = -1
3x + 5y = 21
Step 2: Rewrite Systems
x - y = -1
Add y to both sides: x = y - 1Step 3: Redefine Systems
x = y - 1
3x + 5y = 21
Step 4: Solve for y
Substitution
Substitute in x: 3(y - 1) + 5y = 21Distribute 3: 3y - 3 + 5y = 21Combine like terms: 8y - 3 = 21Add 3 to both sides: 8y = 24Divide 8 on both sides: y = 3What is the radius of a hemisphere with a volume of 324\text{ ft}^3,324 ft 3 , to the nearest tenth of a foot?
Answer:
5.4 ft
Step-by-step explanation:
Given that the volume of the hemisphere sphere, [tex]V= 324 ft^3[/tex].
Let r be the radius of the hemisphere.
As the volume of the hemisphere, [tex]V=\frac {2}{3}\pi r^3[/tex]
By using the given value, we have
[tex]\frac {2}{3}\pi r^3=324[/tex]
[tex]\Rightarrow r^3=\frac{324\times 3}{2\pi} \\\\\Rightarrow r^3=\frac{324\times 3}{2\times3.14} \\\\\Rightarrow r^3=154.78 \\\\\Rightarrow r=\left( 154.78 \right)^{1/3} \\\\[/tex]
[tex]\Rightarrow r=5.4[/tex] ft
Hence, the radius of the hemisphere is 5.4 ft.
The number of students who bring lunch is 45 fewer these the number of students who eat the school lunch. There are more than 485 students who bring lunch. Write an inequality to find the possible number of students,n, who eat the lunch
Answer:

Step-by-step explanation:
there is many ways to do it!! HOPE YOU ACE IT
The number of students, n that possibly eat lunch at school, n = 531 or more students.
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.
Given that the number of students who bring lunch is 45 fewer these the number of students who eat the school lunch. There are more than 485 students who bring lunch.
The number of students who bring lunch, is;
B > 485 students
The number of student who eat lunch in school, E = B + 45
Thus, E > 485 + 45
The number of student that possibly eat lunch in school, E > 530 students.
The number of students, n that possibly eat lunch at school, n = 531 or more students.

What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
There are 10 seniors and 15 juniors in a gym class.
The total number of students will be given as,
Total students = 10 + 15
Total students = 25
Then the ratio of seniors to total students will be given as,
Ratio = Seniors / Total student
Ratio = 10 / 25
Ratio = 2 / 5
The ratio of seniors to total students will be 2: 5.
