Answer:
[tex] \sqrt{12a \: + \: 12b \: - \: 2ab \: + \: 2b {}^{2} } [/tex]
Step-by-step explanation:
(a²-b²) / (a+b) = 12
a² - b² = 12(a+b)
(a-b)² + 2ab - 2b² = 12a + 12b
(a-b)² = 12a + 12b - 2ab + 2b²
a - b =
[tex] \sqrt{12a \: + 12b \: - 2ab \: + \: 2b {}^{2} } [/tex]

Step-by-step explanation:
A triangular prism has a base that is an isosceles triangle with sides 14 cm, 14cm , base 9 cm , and height 13 cm. The height of the prism is 32 cm. What is the surface area of this prism?
Answer:
Surface area of prism = 1301 cm²
Step-by-step explanation:
A triangular pyramid has 3 rectangular sides and 2 triangular sides.
Now, we are told that the triangular side is isosceles.
This means that two of the rectangular sides which share a side with the equal side of the triangle are equal as well as the 2 triangular sides.
Surface area of prism = 2(area of triangular face) + 2(area of rectangle sharing one side with the equal side of the triangle) + (area of rectangle sharing side with the unequal side of the triangle).
Area of triangle = ½ × base × height
Area of triangle = ½ × 9 × 13 = 58.5 cm²
Since height of prism is 32 cm, then;
area of rectangle sharing one side with the equal side of the triangle = 32 × 14 = 448 cm²
area of rectangle sharing side with the unequal side of the triangle = 32 × 9 = 288 cm²
Thus;
Surface area of prism = 2(58.5) + 2(448) + 288
Surface area of prism = 1301 cm²

How many unit cubes are on each layer of this cube
There are 16 cubes in each layer.
What are cube?A cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. Viewed from a corner it is a hexagon and its net is usually depicted as a cross.
Given that, a cube,
Since, we know that, all sides of a cube are equal and the cross-section of the cube is a square,
Therefore, counting the cubes of the front face,
4 cubes vertical and 4 cubes horizontal,
Therefore, total cube in front face = 4×4 = 16
Therefore, cubes in each layer is 16.

What is the difference, in meters, between the length of the longest line and the length of the shortest line?
Answer:
[tex]Range = 3.169m[/tex]
Step-by-step explanation:
Given
See attachment for complete question
Required
Determine the difference between the shortest and the longest
This question implies that we calculate the range.
[tex]Range = Longest - Shortest[/tex]
From the table, we have:
[tex]Longest = 8.7m[/tex]
[tex]Shortest = 5.531m[/tex]
So, we have:
[tex]Range = 8.7m- 5.531m[/tex]
[tex]Range = 3.169m[/tex]

C. Two of the three integers must be even.
D. The product must be even.
E. Two of the three integers must be odd.

Answer:
d
Step-by-step explanation:
integer is a whole number
imagine the sum of the first set of 3 integers = 4 + 5 + 6
product = 4 x 5 x 6 = 120
imagine the sum of the 2nd set of 3 integers = 6 + 7 + 8 = 21
6 x 7 x 8 = 3364

Answer:
[tex] m\angle SXW =113\degree [/tex]
Step-by-step explanation:
In circle with center X, VS is diameter.
So [tex] \widehat {SWV} [/tex] is a semicircular arc.
[tex] \therefore m\widehat{SWV} = 180\degree [/tex]
[tex] \therefore (12x+7)\degree + (21x +8)\degree = 180\degree [/tex]
[tex] \therefore (33x+15)\degree = 180\degree [/tex]
[tex] \therefore 33x+15 = 180 [/tex]
[tex] \therefore 33x = 180-15 [/tex]
[tex] \therefore 33x = 165 [/tex]
[tex] \therefore x =\frac{165}{33} [/tex]
[tex] \therefore x =5 [/tex]
[tex] m\angle SXW =m\widehat{SW} [/tex]
(Measure of central angle is equal to the measure of its corresponding minor arc)
[tex] m\angle SXW =(21x + 8)\degree [/tex]
[tex] m\angle SXW =(21\times 5+ 8)\degree [/tex]
[tex] m\angle SXW =(105+ 8)\degree [/tex]
[tex] m\angle SXW =113\degree [/tex]

The electronics store is offering 30% off all accessories. If Lisa saves $9.00 buying four charging cords, what was the original price of the cords?
Answer:
Cost of each cord = $7.5
Step-by-step explanation:
Given:
Discount rate = 30% = 0.30
Amount save by Lisa = $9
Number of charger = 4
Find:
Cost of each cord
Computation:
Total cost of 4 charger = Amount save by Lisa[1/Discount rate]
Total cost of 4 charger = 9[1/0.30]
Total cost of 4 charger = $30
Cost of each cord = Total cost of 4 charger / Number of charger
Cost of each cord = $30 / 4
Cost of each cord = $7.5

The scale on a map is 1 in: 55 miles. What is the distance on the map between two cities that are 99 miles apart?
Answer:
1.8 inches
Step-by-step explanation:
Create a proportion where x is the distance on the map
[tex]\frac{1}{55}[/tex] = [tex]\frac{x}{99\\}[/tex]
Cross multiply and solve for x
55x = 99
x = 1.8
So, the distance on the map is 1.8 inches
Answer:
1.8 inches
Step-by-step explanation:
Scales on a map always represent the direct proportion.
Compare the distances as fractions:
Inches on the map
________________ = [tex]\frac{1}{55} = \frac{x}{99}[/tex]
Miles on the ground
[tex]x = \frac{1x99}{55}[/tex]
[tex]x = \frac{99}{55}[/tex]
[tex]x = \frac{9}{5} = 1\frac{4}{5}[/tex]
x = 1.8 inches
