Answer:
If your shape is a regular polygon (such as a square in the example above) then it is only necessary to measure one side as, by definition, the other sides of a regular polygon are the same length. It is common to use tick marks to show that all sides are an equal length.

1. A cube measures 4cm on each side and has a mass of 12 grams. What is the
density of the cube?
Explanation:
First we need to find the volume of the cube
volume = length*width*height = 4*4*4 = 64 cubic cm
Then we'll divide the mass over this volume to get the density
density = mass/volume
density = (12 grams)/(64 cm^3)
density = (12/64) grams per cm^3
density = 0.1875 grams per cm^3
The notation cm^3 is another way of saying "cubic centimeter" as shorthand.

Trying to factor by splitting the middle term
2.1 Factoring 2y2-5y-8
The first term is, 2y2 its coefficient is 2 .
The middle term is, -5y its coefficient is -5 .
The last term, "the constant", is -8
Step-1 : Multiply the coefficient of the first term by the constant 2 • -8 = -16
Step-2 : Find two factors of -16 whose sum equals the coefficient of the middle term, which is -5 .
-16 + 1 = -15
-8 + 2 = -6
-4 + 4 = 0
-2 + 8 = 6
-1 + 16 = 15
Observation : No two such factors can be found !!

Answer:
7x = y - 7
Step-by-step explanation:
→ Replace the f(x) with a y
[tex]y=\frac{x-7}{x}[/tex]
→ Make x the subject by first multiplying both sides by x
[tex]xy=x-7[/tex]
→ Now rearrange to get all x on one side
[tex]x-xy = 7[/tex]
→ Factorise
[tex]x(1-y)=7[/tex]
→ Divide both sides by 1-y
[tex]\frac{7}{1-y}[/tex]
Write the explicit rule of the arithmetic sequence that has a first term of 3 and a fourth term of 18
Answer:
[tex]a_{n}[/tex] = 5n - 2
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₄ = 18 , then
a₁ + 3d = 18 , that is
3 + 3d = 18 ( subtract 3 from both sides )
3d = 15 (divide both sides by 3 )
d = 5
Then
[tex]a_{n}[/tex] = 3 + 5(n - 1) = 3 + 5n - 5 = 5n - 2 ← explicit rule

Answer:
1 + √2Step-by-step explanation:
Start with the inner root:
81 + 2√1568 = 49 + 2*28√2 + 32 = 7² + 2*7*4√2 + (4√2)² = (7 + 4√2)²Move to next one:
2 + 7 + 4√2 = 1 + 2*2√2 + 8 = 1² + 2*2√2 + (2√2)² = (1 + 2√2)²The last one:
2 + 1 + 2√2 = 1 + 2√2 + 2 = 1² + 2*1*√2 + (√2)² = (1 + √2)²The root of the last one is:

find the number by which 5400 must be multiplied so that the product is a perfect cube.
Also find the cube root of the number obtained.
( Show workings )
Answer:
Step-by-step explanation:
The easiest way (or the most reliable way) is to factor the given number into primes
5400 = 2 * 2 * 2 * 3 * 3 * 3 * 5 * 5
I cheated a little bit. 54 = 2 * 27 which is 2 * 3 * 3 * 3
100 = 2 * 2 * 5 *5
Combine the two parts and you get the factors I gave you.
Now you have to have the numbers go into groups of three. The only adjustment needed is 5 * 5 and one more 5
So the perfect cube is 5400 * 5 = 27000
Does that work? It should
27000^(1/3) = 3 * 10 = 30
So the cube root of 27000 is 30.

Hi! I'm happy to help!
We know that 2y=150, so we can divide both sides by 2 to find the angle of y
2y=150°
÷2 ÷2
y=75°
So, y=75°.

El kilogramo de harina necesario para hacer 3 1/2 kg de mantequilla para pasteles es 1 2/5 kg
1 kg de mantequilla de bizcocho = 2/5 kg de harina
Deje que la cantidad de kg de harina necesaria para hacer 3 1/2 kg de mantequilla de torta = b
Expresando Matemáticamente:
1 kg = 2/5
1 kg = 2/53 1/2 kg = b
1 = 2/5
3 1/2 = b
Multiplicar en cruz:
b = 3,5 × 0,4
b = 1,4
Por lo tanto, el kilogramo de harina requerido para hacer 3 1/2 kg de mantequilla para pasteles es 1 2/5 kg

Hello there!
We are given the equation:
[tex] \displaystyle \large{ |4x - 1| = 1}[/tex]
Definition/Property
[tex] \displaystyle \large{ |a| = \sqrt{ {a}^{2} } } \\ \displaystyle \large{ |a| = b \longrightarrow a = \pm b} \\ \displaystyle \large{ |a| = \begin{cases} a \: \: (x \geqslant 0) \\ - a \: \: (a < 0) \end{cases}}[/tex]
First, cancel the absolute value sign and write plus-minus beside 1.
[tex] \displaystyle \large{ |4x - 1| = 1} \\ \displaystyle \large{ 4x - 1 = \pm 1} \\ [/tex]
Break in two cases.
[tex] \displaystyle \large{ 4x - 1 = \begin{cases} 1 \\ - 1 \end{cases}} \\ \displaystyle \large{ 4x = \begin{cases} 1 + 1 \\ - 1 + 1 \end{cases}} \\ \displaystyle \large{ 4x = \begin{cases} 2 \\ 0 \end{cases}} \\ \displaystyle \large{ x = \begin{cases} \frac{2}{4} \\ \frac{0}{4} \end{cases}}[/tex]
Therefore, x = 0 or 1/2
