What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
Here the given expression is :
3(a-2b)
where, a = -3
and, b = -12
Now, substitute the value of a and b in the given expression :
3(a-2b)
= 3(-3-2x -12)
= 3(-3 + 24)
= 3(21)
= 63
Therefore, the solution of the given expression is 63.

Explain why 0 divided by any number is either 0 or infinity.
Answers
Step-by-step explanation:
Division as the inverse of multiplication
But any number multiplied by 0 is 0 and so there is no number that solves the equation. ... In general, a single value can't be assigned to a fraction where the denominator is 0 so the value remains undefined.
Answer:
0 divided by itself is undefined so we use infinity or 0 to describe it because infinity has no limits and it doesn’t really exist so I wouldn’t say it equals infinity or 0 but it is undefined. I hope it helps! Let me know if you need more help :D

can be written as
→ 8(0.1) + 7(0.01) + 1(0.001)
→ 0.8 + 0.07 + 0.001
→ 0.871
hope this answer helps you dear...take care and may u have a great day ahead!
Answer:
B. 0.871
Step-by-Step:
First multiply eight by one tenth = 8 x 0.1= 0.8
Then multiply seven by one hundredth= 7 x 0.01= 0.07

Answers
Answer:
(6 - √ 100 - 6 * 6) 3 - 9 ÷ 3 = -64003/1 = -64003
Step-by-step explanation:
1.Square root: sqrt(100) = √ 100 = 10
2.Subtract: 6 - the result of step No. 1 = 6 - 10 = -4
3.Multiple: 6 * 6 = 36
4.Subtract: the result of step No. 2 - the result of step No. 3 = -4 - 36 = -40
5.Exponentiation: the result of step No. 4 ^ 3 = (-40) ^ 3 = -64000
6.Divide: 9 / 3 = 3
7.Subtract: the result of step No. 5 - the result of step No. 6 = -64000 - 3 = -64003
