Answer:
The square of this expression is written as ( a − b ) 2 in mathematical form and it is expanded as a 2 − 2 a b + b 2 mathematically. In mathematics, this algebraic identity is used as a formula and it is called in the following three ways. The square of difference of the terms formula.
Step-by-step explanation:
The last digit in the product will be '0' because anything multiplied by zero will be zero. In this case you are using larger numbers, however this will always be the case when multiplying with any number with zero.
Sum of interior angle of a triangle is 180 degrees.
2x + 4x + 9x = 180
15x = 180
x = 180/15 = 12
2x = 2 x 12 = 24
4x = 4 x 12 = 48
9x = 9 x 12 = 108
the measures of the angles are : 24 degrees, 48 degrees ,108 degrees
