Jenna is correct and Billy is wrong because the equation was not converted to a quadratic form.
Form of quadratic equationThe form of quadratic equations is given as
ax2 + bx + c = 0
So, for the quadratic equation, we have
x² - x = 12
Let's make it into quadratic form
x² - x - 12 = 0
Bill solved it as
x(x - 1) = 12
This is wrong, because quadratic equations must be written in the form before solving for the variables
Jenna solved it as
x 2 - x - 12 = 0
Jenna is correct because she converted the equation to a quadratic form before solving for the variables.
Thus, Jenna is correct and Billy is wrong because the equation was not converted to a quadratic form.

Step-by-step explanation:
The boxes that only have a half-shaded in can be counted as 0.5.
If you combine these half-shaded boxes, it will give you 1.
Since there are 8 half-shaded boxes, that equal to 0.5, you can multiply these together and get 4.
Add this to the 20 whole boxes, and you will get 24.

Find the number of terms and the degree of this polynomial. -9
[tex]9 {r}^{9} [/tex]
Number of terms: Degree:
Answers:
Number of terms: 1Degree: 9===============================================
Explanation:
This is consider a monomial since we only have one term. Terms are separated by a plus sign, so something like 5x^2+10x has two terms.
The degree of a polynomial is the largest exponent when dealing with single variables. In the case of 9r^9, the largest exponent is 9, so the degree is 9. Going back to an example like 5x^2+10x, the largest exponent is 2 so this is the degree of this example.

what are the missing values, and what is the equation for the table
Answer:
Step-by-step explanation:
This is a linear equation. Mx+b=y.
m=slope
x=x coordinate
y=y coordinate
b=y intercept (where x=0)
For this problem, you need to plug in 2 "coordinates", ex (1,16), and (0,__). You would need to find the slope, which would be y2-y1/x2-x1 (find two "coordinates" and then put it in, order doesn't matter.)

Answer:
see attached for table valuesexponential equation: y = 8·2^x; linear equation: y = 60x -44Step-by-step explanation:
Two points are not sufficient to define a graph, so the equation could be anything that gives the listed values.
We note that the given y-values are powers of 2. Specifically, they are 2^4 and 2^8. These powers differ by 4, just as the corresponding x-values differ by 4. This suggests an exponential equation might be good fit:
y = 2^(x+3)
Simplified, this is ...
y = 8·2^x . . . . . exponential equation for table values

Alternate solution
Often, when only two points are given, a linear function is indicated. We can use the two given points in the 2-point form of the equation for a line to find what the linear equation might be.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (256 -16)/(5 -1)(x -1) +16 . . . . with values filled in
y = 240/4(x -1) +16 . . . . . . . . . . . find the ratio
y = 60x -60 +16 . . . . . . . . . . . . . eliminate parentheses

A rectangle has a length of √7 meters and a width of (2√5 - √15) meters. What is its area?
Mensuration
Given :-A rectangle has length of √7 meters and width of ( 2√5 - √15 ) meters.
To Find :-Area of rectangle.
Formula to be Used :-[tex]\boxed{Area\:of\:rectangle=Length \times Width}[/tex]
Solution :-It is given that,
Length = √7 meters
Width = ( 2√5 - √15 ) meters
Applying formula,
Area = Length × Width
Area = √7 × ( 2√5 - √15 ) sq. meters
Area = ( 2√5 × √7 - √15 × √7 ) sq. meters
Area = ( 2√( 5 × 7 ) - √( 15 × 7 ) ) sq. meters
Area = ( 2√35 - √105 ) sq. meters
Answer :-So, area of given rectangle is
( 2√35 - √105 ) sq. meters

2x – 5 > 3 or 11 – 3x > -2
Answer:
x > 4 and x <3
Step-by-step explanation:
Given the system of inequalities
2x – 5 > 3 or 11 – 3x > -2
for 2x – 5 > 3
2x > 3+5
2x>8
x>8/2
x> 4
For 11-3x > -2
-3x > 2-11
-3x > -9
x < -9/-3
x<3
hence the result will be x > 4 and x <3
The difference of x and 4 (Algebraic expression)
Answer:
x - 4
Step-by-step explanation:
The difference means subtraction
The algebraic expression of the phrase is x-4.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
Given phrase:
The difference of x and 4.
Here, we have the phrase difference.
So, we will use the subtraction operation.
So, the algebraic expression,
x - 4.
Therefore, x -4 is the algebraic expression.

w = 5÷2
w = 2.5
1440 tons of grain where brought to a silo over two days. On the second day 80 percent of the amount of the amount of the grain delivered during the first day where brought in. How many tons where delivered on the first day
Answer:
1152 tons of grains
Step-by-step explanation:
We are told in the above question:
Total number of grains = 1440 tons of grain
On the second day 80 percent of the amount of the amount of the grain delivered during the first day where brought in.
Hence,
The number of grains brought in during the first day = 80% × 1440 tons
= 80/100 × 1440 tons
= 1152 tons of grains

Answer:
x = 7, y = 24
Step-by-step explanation:
23x -16 + 8x - 21 = 180 because they are supplementary angles
31x - 37 = 180
31x = 217
x = 7
23(7)-16 = 7y - 23 because they are vertical angles
168 = 7y
y = 24
