Answer:
[tex](x+4)^2+3=0[/tex]
Step-by-step explanation:
Hey there!
Standard form is what this equation is in
Standard form is this: [tex]ax^2+bx+c[/tex]
So order to complete the square, you need to take the [tex]b[/tex] term out of the equation, divide it by two, and then square it
In this case, the [tex]b[/tex] term is 8
We need to divide 8 by 2 ---> 4
Then square 4 ---> 16
So now you should add 16 to both sides
[tex]x^2+8x+16+19=16[/tex]
Now you can simplify the LHS
[tex](x+4)^2 +19=16[/tex]
Now you subtract 16 from both sides
[tex](x+4)^2+3=0[/tex]
So this is as far as you can go since you cannot take the square root of a negative number

For a repeated-measures study, a small variance for the difference scores indicates that the treatment effect is consistent across participants.
A. True
B. False
The statement that a small variance for the difference scores implies that the treatment effect is consistent is true
How to determine the truth value of the statement?The variance of a dataset is used to measure the spread and the average squared deviations from the mean of the dataset.
The smaller the variance of a repeated study, the closer the dataset set are from the mean of the dataset.
This means that a small variance indicates a consistent data
Hence, the given statement is true

Theresa uses a unique box in the shape of a trapezoidal prism for her specialty candles. The area of the base of the box for the smaller candle is 125 cm2 and the box is 12 cm tall. The box used for the larger candle has a base whose area is 160% that of the smaller box, and it is 6 centimeters taller.
What percent of the volume of the smaller box is the volume of the larger box?
Answer:
The volume of the larger box is 240% that of the volume of the smaller box.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables
Volume of smaller box = area of base * height = 125 cm² * 12 cm = 1500 cm³
Volume of larger box = area of base * height = (1.6 * 125 cm²) * (12 + 6) cm = 3600 cm³
Ratio of volume = 3600/1500 = 2.4 = 240%
The volume of the larger box is 240% that of the volume of the smaller box.

1. Landing on a shaded portion and landing on a 3.
2. Landing on an unshaded portion and landing on a number
less than 2.
The explanation for 1:
Landing on a shaded portion means landing on 1 or 4.
Landing on 3 is not possible and it will be only on 3. So, these events have no intersection.
