Amira is solving the equation x2 – 6x = 1. Which value must be added to both sides of the equation to make the left side a perfect-square trinomial?
a. –9
b. 8
c. 9
d. 36

Answers

Answer 1

c. 9

To complete the square, you take half of the coefficient of b and square it. It's important to note that the value being added will always be positive.

[tex] {ax}^{2} + bx + c[/tex]

[tex]b = - 6[/tex]

[tex] - 6 \div 2 = - 3[/tex]

[tex] = {( - 3)}^{2} [/tex]

[tex] = 9[/tex]

An art student uses a roll of wallpaper to decorate two gift boxes. The student will use 3 1 3 yards of paper for one box and 5 6 yard of paper for the other box. The paper must be cut into pieces that are 1 6 yard long. How many pieces will the student cut to use for the gift boxes?

Answers

Answer:

25 pieces

Step-by-step explanation:

Given

[tex]Box_1 = 3\frac{1}{3}[/tex]

[tex]Box_2 = \frac{5}{6}[/tex]

[tex]Pieces = \frac{1}{6}[/tex] yard

Required

Determine the number of pieces

First, we need to determine the total yards of paper

[tex]Total = Box_1 + Box_2[/tex]

[tex]Total = 3\frac{1}{3} + \frac{5}{6}[/tex]

[tex]Total = \frac{10}{3} + \frac{5}{6}[/tex]

[tex]Total = \frac{20 + 5}{6}[/tex]

[tex]Total = \frac{25}{6}[/tex]

Divide by the size of the pieces to get the number of pieces

[tex]Number = Total/Pieces[/tex]

[tex]Number = \frac{25}{6} / \frac{1}{6}[/tex]

[tex]Number = \frac{25}{6} * \frac{6}{1}[/tex]

[tex]Number = \frac{25}{1} * \frac{1}{1}[/tex]

[tex]Number = 25[/tex]

How old will you be when you have Received a total Of $4000 from aunt Isabell?

Answers

Answer:

20 years old

Step-by-step explanation:

Given

Base Amount = $10

Additional Amount = $20

Required

Determine the number of years where the total will accumulate to $4000

This question represents Sum of an AP series.

[tex]S_n = \frac{n}{2}(2a + (n - 1)d)[/tex]

Such that:

[tex]S_n = 4000[/tex]

[tex]a = 10[/tex]

[tex]d = 20[/tex]

Substitute these values in the above formula:

[tex]4000 = \frac{n}{2}(2 * 10 + (n - 1) * 20)[/tex]

[tex]4000 = \frac{n}{2}(20 + 20n - 20)[/tex]

[tex]4000 = \frac{n}{2}(20n)[/tex]

[tex]4000 = \frac{20n^2}{2}[/tex]

[tex]4000 = 10n^2[/tex]

Divide through by 10

[tex]400 = n^2[/tex]

Take square root of both sides

[tex]20 = n[/tex]

[tex]n = 20[/tex]
