HEY!! remember that if a number has ^2, it basically means it's multiplied by itself. for example:
5^2 = 5 x 5
aka, 25.
You can use this to check each of the answers in your formula, like this:
if x=6, then:
x^2 < 100
6 x 6 = 36
36 < 100
A is one of your correct answers!
Also remember, if you multiply a negative by a negative, it becomes positive.
-5 x -5 = 25
-10 x -10 = 100

b) -3.5, 3.5, 3.5
c) 5 1/2, -5 1/2, 5 1/2
Step-by-step explanation:
The opposite number of a value is the number that adds to it to make zero. To find the opposite of a number you need to switch the sign, either from positive to negative or vice versa. The absolute value of a number is the distance from zero it is. Since distance cannot be negative you just need to take the number and make it positive.

Lin divides the polynomial 2x^2 -4x+1 by 4 and gets 0.5x^2 -x + 0.25. is 0.5x^2 - x +0.25 a polynomial
Answers
Answer: yes
Step-by-step explanation:
The expression 0.50 x² - x + 0.25 is a polynomial.
It is given that Lin divides polynomial 2x² - 4x + 1 by 4 and gets 0.5x² - x + 0.25.
We have to find out that whether the expression given is a polynomial ?
What do you mean by a polynomial ?
Polynomials are algebraic expressions that consist of variables and coefficients e.g., polynomial with one variable is x² + x - 12.
As per the question ;
Lin divides polynomial 2x² - 4x + 1 by 4 and gets 0.5x² - x + 0.25
Let's check ;
(2x² - 4x + 1 ) ÷ 4
= [tex]\frac{2x^{2} }{4}[/tex] - [tex]\frac{4x}{4}[/tex] + [tex]\frac{1}{4}[/tex]
= [tex]\frac{x^{2}}{2}[/tex] - x + 0.25
or
= 0.50 x² - x + 0.25
or a form of polynomial i.e., ax² + bx + c.
Thus , the expression 0.50 x² - x + 0.25 is a polynomial.

Find the intercepts of the given line:
y=−6x+21
Answers
Answer:
x-intercept = 3.5y-intercept = 21Step-by-step explanation:
x-intercept is for y = 0
y-intercept is for x = 0
Substitute
For y = 0
-6x + 21 = 0 |subtract 21 from both sides
-6x = -21 |divdie both sides by (-6)
x = -21/(-6)
x = 21/6
x = 3.5
For x = 0
y = -6(0) + 21
y = 0 + 21
y = 21
So (0,21) is the starting point and if you rise -6 and run 1 you get (15,1) and you keep doing that until u get a line
Trey’s grandmother has a framed picture with side lengths that are 12 inches. Trey wants to know how much wall space is needed for the picture.
What is the area of a picture with side lengths that are 12 inches? Use the formula A= s^2, where s is the length of one side.
A. 12in.^2
B. 144in.^2
C. 24in.^2
D. 288in.^2
Answers
Answer:
B, 144in.^2 :)
Step-by-step explanation:
The area of a picture with side lengths that are 12 inches is 144 inches²
It should be noted that a square has four sides that are equal. In this case, we've been given the side of one of the lengths to be 12 inches.
Therefore, the square of the sides will be 12 inches multiplied by 12 inches. This will then be:
Area of a square = side ²
Area = 12 inches × 12 inches
Area = 144 inches²
Therefore, the area of a picture with side lengths that are 12 inches is 144 inches ²
