43 tens = 43 x 10 = 430
3 tens = 3 x 10 = 30
Multiply the two numbers together
430 x 30 = 12900
12900 is your answer
hope this helps
Multiplication property of equality can be used to solve: 
Step-by-step explanation:
First of all, lets define the multiplication property of equality
The multiplication property of equality states that if one side of an equation is multiplied with any number the other side is also multiplied with the number.
Given equations are:
By observing the equations we can see that only third equation has a fraction in it so it has to be multiplied with -2 for solution
Hence,
Multiplication property of equality can be used to solve:

Find the area of the triangles and smal ler square and add them together ; and find the area of the complete square and set them equal to each other (these are known truths)
triangle: l×w /2
square: s^2
There are 4 triangles so
4 (1/2ab)+c^2= (a+b)(a+b)
simplify
2ab+c^2= a^2+2ab+b^2
-2ab both sides
c^2=a^2+b^2
tada!! it's proven :)
You multiply both of the equations until you have two of the same term the same like for example, say I have 4x and 5x. You want to multiply until both have the same number, so multiply 5x by four, then multiply 4x by five, and you will get 20x, then both of those cancel out and you will be left with the other variable, and you just solve like a normal equation.
