Answer:

-6x² - 11x - 3

Step-by-step explanation:

This represents the product of the two functions.

(-2x-3)(3x+1) = -(2x+3)(3x+1) = -(6x² + 11x + 3) = -6x² - 11x - 3

Answer:

Remaining amount is 6.25 gram

Step-by-step explanation:

After one year what you would be left with is 50/2 which is 25 gram

After the second year, you would be left with 50/4 which is 12.5

After the third year what's left is 50/8 i.e 6.25

Answer:

Base, b = 4.5 yards

Step-by-step explanation:

Given the following data;

Area of triangle = 45 square yards

Height = 20 yards

To find the base of the triangle;

Mathematically, the area of a triangle is given by the formula;

Area of triangle = ½ * b * h

Where;

b is the base of the triangle.

h is the height of the triangle.

45 = ½ * b * 20

90 = 20b

Base, b = 90/20

Base, b = 4.5 yards

Answer:

  (b)  28

Step-by-step explanation:

The total of the 3 numbers will be 3×15 = 45. Then the third number is ...

  45 -7 -10 = 28

9514 1404 393

Answer:

  {587, 1}

Step-by-step explanation:

The sum will be minimized when the second number is as close to zero as is allowed. If the numbers must be positive integers, the sum is minimized when the numbers are {587, 1}.

If the numbers may be real numbers, then the values that minimize the sum are {588-, 0+}

_____

The "cost" of taking a unit from the sum 588 and assigning it to the second number is that the sum of first and 3 times the second goes up by 3. In order to minimize that sum, the second number must be minimized.

Answer:

g. True

h. False

i. False

Step-by-step explanation:

g.

[tex]\frac{1}{14}[/tex] is half of [tex]\frac{1}{7}[/tex]

This would be true because half of a number can be found by multiplying by [tex]\frac{1}{2}[/tex]

If you multiplied [tex]\frac{1}{7} * \frac{1}{2}[/tex]

The numerator is 1 * 1 which is 1

And then the denominator is 7 * 2 which is 14

That would give you [tex]\frac{1}{14}[/tex]

h.

The products of two reciprocals is 0

This is not true

Reason being, reciprocals are just the number flipped. If you times the number by itself, you don't get 0, you get 1.

Ex: [tex]\frac{2}{8}[/tex]

Its reciprocal is [tex]\frac{8}{2}[/tex]

So multiply them together

[tex]\frac{2}{8}* \frac{8}{2}[/tex]

2 * 8 = 16

8 * 2 = 16

[tex]\frac{16}{16} = 1[/tex]

i.

A whole number does not have a reciprocal

This is incorrect. If you think about it, a whole number is just the number, over 1

Ex: [tex]\frac{6}{1}[/tex]

This is still a whole number even though its written in fraction form because if you divide 6 by 1, your still going to get 6.

If you an write it as a fraction, it has a reciprocal.

The reciprocal in this case would be [tex]\frac{1}{6}[/tex]

Answer:

If cookies are for $1 and brownies are for $2, let number of cookies = x and number of brownies = y

∴ $1*(x*1) + $2*(y*1) = $13

Step-by-step explanation:

1) You can buy 4 brownies for $2 each = 2*4 = $8

The rest you can buy cookies = 5 cookies = $5

$8+$5=$13

2) You can buy 5 brownies and 3 cookies = $10+$3 = $13

3) You can buy 3 brownies and 7 cookies = $6+$7=$13

Equation: -

If cookies are for $1 and brownies are for $2, let number of cookies = x and number of brownies = y

∴ $1*(x*1) + $2*(y*1) = $13

Answer:

72 in²

Step-by-step explanation:

lateral area: the surface area of a 3D figure, but excluding the area of any bases

the lateral area of this prism is the sum of the three rectangular sides.

calculate the third side of the triangle first because it's also the side of one of the rectangle:

√(5² - 4²) = 3

4 × 6 + 5 × 6 + 3 × 6 = 72

Answer:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Answer:

[tex]Sales \ Tax \ Amount = Net \ Price \cdot \frac{Sales \ Tax \ percentage}{100}[/tex]

[tex]21.70 = 331.70 \cdot \frac{sales\ tax \ percentage}{100} \\\\\frac{21.70}{331.70} = \frac{sales\ tax \ percentage}{100}\\\\0.0654 = \frac{sales\ tax \ percentage}{100}[/tex]

Sales Tax Percentage  = 0.0654 × 100 = 6.54%

Answer:

1). All four triangles are right-angled.

3.) All four triangles are congruent.

4) Area of a rhombus = 4 x area of one triangle.

Step-by-step explanation:

If a rhombus is cut into four triangles using diagonals, the three statements that would apply to any rhombus would be that 'all those four triangles would be right-angled,' 'the triangles would be congruent to one another,' and 'area of one triangle * 4 would be equal to the area of the rhombus.'

As we know, the diagonals bisect one another in a rhombus at 90° and the angles opposite to one another are equal. This proves that all four triangles constructed through the diagonals would be ≅ through SSS congruency and perpendicular to one another because the corresponding edges of the congruent triangles are also ≅ . Since the rhombus is divided into four equal parts, the area of one triangle into four would be equals to the area of the rhombus. Thus, options 1, 3, and 4 are the correct answers.

Answer:

60°

Step-by-step explanation:

If it a equilateral triangle

Given:

A figure.

To find:

Whether the pair of angle 3 and angle 5 is adjacent, vertical, or neither.

Solution:

Adjacent angle: If two angles are adjacent to each other, it means they have a common vertex, one common side and they are not overlapping each other, then they are called adjacent angles.

Vertical angles: If two lines intersect each other then the opposite angles are known an vertical angles.

From the given figure it is clear that the angle 3 and angle 5 are neither adjacent nor vertical angles.

Therefore, the correct option is B.
