The length of a rectangle is 4 m shorter than its width. If the perimeter of the rectangle is 18 m, find its length and width.
Group of answer choices
Answers
2(x - 4) + 2x = 18, where x represents the width.
2x - 8 + 2x = 18 (Distribute 2)
4x - 8 = 18 (Add like terms)
4x = 26 (Add 8 to both sides)
x = 6.5 (Divide 4 from both sides)
Length = x - 4 (Length is 4 less m than Width [x - 4])
6.5 - 4 = 2.5 (Substitue in x)
Length = 2.5
The length is 2.5 meters and the width is 6.5 meters.
You can check by adding 2.5 + 2.5 + 6.5 + 6.5 = 18.

Write a quadratic function in standard form with zeros 1 and -10 plzzzz helppp meee
Answers
Answer:
[tex]f(x)=x^2+9x-10[/tex]
Step-by-step explanation:
Standard Form of Quadratic Function
The standard representation of a quadratic function is:
[tex]f(x)=ax^2+bx+c[/tex]
where a,b, and c are constants.
The factored form of a quadratic equation is:
[tex]f(x)=a(x-\alpha)(x-\beta)[/tex]
Where [tex]\alpha[/tex] and [tex]\beta[/tex] are the roots or zeros of f.
The question gives the zeros of the function: 1 and -10. This makes our function look like:
[tex]f(x)=a(x-1)[x-(-10)][/tex]
[tex]f(x)=a(x-1)(x+10)[/tex]
Operating:
[tex]f(x)=a(x^2+10x-x-10)[/tex]
Joining like terms:
[tex]f(x)=a(x^2+9x-10)[/tex]
Since we are not given any more conditions, we choose the value of a=1, thus. the required function is:
[tex]\boxed{f(x)=x^2+9x-10}[/tex]

A school chess club needs to raise at least $750 to attend a state competition. The club has already raised $400 and there are 4 months remaining until the competition. Which inequality and statement can be used to determine the dollar amount the club will need to raise during the remaining months?
Answers
Answer:
400+4n ≥ 750; The club will need to raise an average of $87.50 or more per month.
Step-by-step explanation:
The inequality will be 400+4n ≥ 750 and the club will need to raise an average of $87.50 or more per month.
What is inequality?When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relation between variables and the numbers.
Given that a school chess club needs to raise at least $750 to attend a state competition. The club has already raised $400 and there are 4 months remaining until the competition.
The inequality will be written as,
400+4n ≥ 750
4n ≥ 750 - 400
4n ≥ 350
n ≥ 350 / 4
n ≥ $87.5
