Answer:
The answers are as follows: 12 106 42
Step-by-step explanation:
Given: 
Using BODMAS rule (Bracket, Of, Division, Multiplication, Addition and Subtraction) we would calculate 
separately and 
separately and add them. So we have 
.
Now for the second question: 
. we would get 
Next, 
. This could be written as: 
. Hence the answers.
Answer:
The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.

Answer:
Step-by-step explanation:
The momentum of an object is given by 
, where 
is the mass of the object and 
is the velocity of the object.
What we're given:
- object's mass
- object's momentum
Substituting given values, we can solve for :
Create a system of equations
x + y = 123
5x + y = 343
I use substitution
y = 123 - x
5x + 123 - x = 343
4x + 123 = 343
4x = 220
x = 55
Plug in
x + y = 123
55 + y = 123
y = 68
Check
5x + y = 343
5(55) + 68 = 343
275 + 68 = 343
343 = 343
<span><u><em>Answer:</em></u>
64
<u><em>Explanation:</em></u>
The square of any number can be obtained by multiplied the number by itself.
<u>In other words:</u>
square of x = x</span>²<span> = x * x
For the given, we want to get the square of 8. This means that we will <u>multiply 8 by itself.</u>
Therefore:
square of 8 = 8</span>²<span> = 8 * 8 = 64
Hope this helps :)</span>
