Work out 5/8−2/5 Give your answer in its simplest form.
Answers
First, find the LCD (least common denominator) of the two fractions.
List the multiples of each denominator and find the one that is common.
Multiples of 8: 8, 16, 24, 32, 40
Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40
40 is your LCD.
Second, what can you divide by to make the denominators of each fraction '40'? Whatever you do to the bottom you must do to the top.
Third, multiply.
Fourth, since the denominators are the same now, we can combine them.
Fifth, subtract '25 - 16' to get 9.

Answers
Sphere Vol = 4/3Pi radius^3
Give the 4/3Pi bit a constant - 'C'
Vol = C x radius^3
V1 = C 3^3 = 27C
V2 = C 5^3 = 125C
New Volume = 27C + 125C = 152C
Aproximate radius = cube Root 152 = Approx 5.3

The width of the rectangle with an area x² = 19x + 12 is (4x + 3).
What are the area and perimeter of a rectangle?
The area of a rectangle is the product of its length and width.
The perimeter of a rectangle is the sum of the lengths of all the sides.
We know the area of a rectangle is (length×widh).
Given, A rectangle has an area of 4x² + 19x + 12 and a length of (x + 4).
∴ width of the rectangle is = (4x² + 19x + 12)/(x + 4).
Or, we know that the product of two linear equations is a quadratic so,
4x² + 19x + 12.
4x² + 16x + 3x + 12.
4x(x + 4) + 3(x + 4).
(x + 4)(4x + 3).
So, the width of the rectangle is (4x + 3).

1 inch = 2.54 centimeters
1 inch ... 2.54 cm
x inches = ? ... 50 cm
1 * 50 = 2.54 * x
50 = 2.54 * x
x = 50 / 2.54
x = 19.69 inches
1 foot = 12 inches
1 foot ... 12 inches
y feet = ? ... 19.69 inches
1 * 19.69 = 12 * y
19.69 = 12 * y
y = 19.69 / 12
y = 1.64 feet
The correct result would be 1.64 feet.

Answers
Answer:
x = 11
BD = 10
Step-by-step explanation:
Solving for x
The opposite sides if a parallelogram are equal and parallel.
Hence,
2x - 5 = 17
Collecting like terms:
2x = 17 + 5
2x = 22
x = 11
If E is a midpoint, then BE equals to DE
Since BE = 5, then
BD = 2 * BE
BD = 10
