Answer:
x = -2, 0, 2/3
Step-by-step explanation:
3x³ + 4x² - 4x = 0
x(3x² + 4x - 4) = 0
x(3x² + 6x - 2x - 4) = 0
x(3x - 2)(x + 2) = 0
ZEROs
x = 0
3x - 2 = 0
x = 2/3
x + 2 = 0
x = -2

Answer:
Answer:
3.5 fluid ounces
Step-by-step explanation:
In this question, we are asked to calculate the capacity in fluid ounce of a cone-shaped cup.
To solve this, we need to calculate the volume of the cup.
Mathematically, the volume of a cone =
1/3 * π * r^2 * h
Where r = d/2 = 2.7/2 = 1.35 inches
h = 3.3 inches
By substituting this, we have
V = 1/3 * 3.14 * 1.35^2 * 3.3 = 6.3 cubic inch
Now we proceed to calculate the capacity
From the question, we are told that ;
1 fluid ounce = 1.8 cubic inch
This means
x fluid ounce = 6.3 cubic inch
x = 6.3/1.8
x = 3.5 fluid ounces

△ABC has interior angles with measures x°, 100°, and 70°, and △DEF has interior angles with measures y°, 70°, and 50°.
Using the given information, which statement is true?
The two triangles are not similar because x≠y .
The triangles are similar because they each have an interior angle with a measure 70°.
The two triangles are not similar because the interior angles are congruent but the side lengths are different.
The two triangles are not similar because y = 60 so it is impossible to have three congruent angles.

Eddie purchased 15 boxes of paper clips and 7 packages of index cards for a total of $55.40. Finn bought 12 boxes of paper clips and 10 packages of index cards for $61.70. Find the cost of one box of paper clips and one package of index cards
The cost of one box of paper clips is $1.85 and the cost of one package of index cards is $3.95
Step-by-step explanation:
Eldora and Finn went to an office supply store together
Eldora bought 15 boxes of paper clips and 7 packages of index cards for a total cost of $55.40
Finn bought 12 boxes of paper clips and 10 packages of index cards for a total cost of $61.70
We need to find the cost of one box of paper clips and the cost of one package of index cards
Assume that the cost of one box of paper clips is $x and the cost of one package of index cards is $y
∵ x represents the cost of one box of paper clips
∵ y represents the cost of one package of index cards
∵ Eldora bought 15 boxes of paper clips and 7 packages of
index cards for a total cost of $55.40
∴ 15x + 7y = 55.4 ⇒ (1)
∵ Finn bought 12 boxes of paper clips and 10 packages of
index cards for a total cost of $61.70
∴ 12x + 10y = 61.7 ⇒ (2)
Now we have system of equations to solve it
Multiply equation (1) by -10 and equation (2) by 7 to eliminate y
∵ -10(15x) + -10(7y) = -10(55.4)
∴ -150x - 70y = -554 ⇒ (3)
∵ 7(12x) + 7(10y) = 7(61.7)
∴ 84x + 70y = 431.9 ⇒ (4)
Add equations (3) and (4)
∵ (-150x + 84x) + (-70y + 70y) = (-554 + 431.9)
∴ -66x = -122.1
- Divide both sides by -66
∴ x = 1.85
Substitute the value of x in equation (1) or (2) to find y
∵ 12(1.85) + 10y = 61.7
∴ 22.2 + 10y = 61.7
- Subtract 22.2 from both sides
∴ 10y = 39.5
- Divide both sides by 10
∴ y = 3.95
The cost of one box of paper clips is $1.85 and the cost of one package of index cards is $3.95

The first three terms of an arithmetic sequence are as follows.
Answer:
16,20
Step-by-step explanation:
As shown, you add four by each.
4+4=8
8+4=12
So, 12+4=16
16+4=20
Answer:
16 and 20
Step-by-step explanation:
In the arithmetic squence, we can tell that 4 is being added to each term.
Thus, we obtain the following rule:
4x [Where "x" is the xth term]To find the next two terms in the sequence, we need to determine the fourth and fifth term of the sequence. Let us substitute the "4" and "5" in the rule to determe the next two terms in the sequence.
Determining the 4th term of the sequence:
⇒ 4x
⇒ 4(4)
⇒ 16
Determining the 5th term of the sequence:
⇒ 4x
⇒ 4(5)
⇒ 20
Thus, the next two terms are 16 and 20.

The area of the quadrilateral is equal to 15 square units.
What is an area?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the quadrilateral in a two-dimensional plane is called the area of the quadrilateral. A quadrilateral is a four-sided polygon with four edges and four corners in geometry.
Given that the quadrilateral has a height of 3 units, the base is 3 units and the upper sides are 7 units.
The area of the quadrilateral is calculated by the formula,
Area = (1/2) x h x (a + b)
Substitute the values in the formula and calculate the area,
Area = (1/2) x 3 x (7 + 3)
Area = (10 / 2) x 3
Area = 5 x 3
Area = 15 square units

The stem-and-leaf plot for the list of test grades is created below.
What is Stem and leaf plot?A stem-and-leaf plot is a graphical representation of data that organizes values into a format that displays both the individual data points and their corresponding frequency. It is a way to represent a set of numerical data visually.
To create a stem-and-leaf plot, we separate each number into a stem and a leaf. The stem represents the tens digit, and the leaf represents the ones digit.
Here is the completed stem-and-leaf plot for the given test grades:
4 | 2
6 | 7
7 | 3, 8, 8
8 | 2, 4, 6, 6
9 | 1, 4, 9
In this plot, the stem represents the tens digit, and the leaves represent the ones digit.
For example, the grade 73 is represented as 7 as the stem and 3 as the leaf. The grade 82 is represented as 8 as the stem and 2 as the leaf.
