What are scale drawings? can you give an example?

Answers

Answer 1

Answer: Scale Drawings are drawings that are used to show the true size of something.
Scale drawings are most commonly used in maps, or in large scale drawings. These show the scale of something. It may show that 1cm is equivalent to 1km, which would allow someone to measure the map to see how far the distance it. It also allows a map to be made smaller, and less detailed- making it often easier to read.
Hope this helps :)

6x(2x2 – 3) – 1(2x2 – 3)
6x(2x2 + 3) + 1(2x2 + 3)

Answers

Hello,
Answer A

12x^3-2x²+18x-3
=2x²(6x-1)+3(6x-1)
=(6x-1)(2x²+3)

The factorization of the given expression by grouping yields(6x-1)(2x²+3).

What is factorization?

Factorization is a way in which the common factors of the terms in an algebraic expression are found. We have the expression 12x^3-2x²+18x-3 in which are to factorize by grouping.

In order to carry out this factorization by grouping we have to perform the following steps;

Identify common factors which are 2x^2 and 3
Apply the common factors to two groups of the portions of the expression as shown;

12x^3-2x²+18x-3

2x²(6x-1)+3(6x-1)

(6x-1)(2x²+3)

How would I write 8.21 as a mixed number?

Answers

we know that

A mixed number is a number consisting of a whole number and a proper fraction

we have

$8.21$

$8.21=8+0.21=8+(21)/(100)=8(21)/(100)$

therefore

the answer is

$8(21)/(100)$

The value of mixed number of number 8.21 is,

⇒ 8 (21 / 100)

We have to given that;

A number is,

⇒ 8.21

Now, We can simplify as;

⇒ 8.21

⇒ 8.21 × 100 / 100

⇒ 821 / 100

⇒ 8 21/100

Therefore, The value of mixed number of number 8.21 is,

⇒ 8 (21 / 100)

G(2)=9 since 2(2)+5=9

The difference of 9 times a number and 2 is 67.Which equation below can be used to find the unknown number?

Answers

the total is 67 so you would write that out
67=
Next you can write out 9 times a number. you can let that unknown number be n(you can use any variable you like). So now you would have
67=9n
You still have to subtract 2 from the 9n so plug that in
67=9n-2
Your answer would be 67=9n-2
