Answer:
b= 69
Step-by-step explanation:
total inside angles = 900
because (7-2)*180 = 900
plus them all and set it = 900
you will get b= 69
An expression is formed of numbers, variables, and mathematical operations. The expression that is equivalent to 35m²-63 is 7(5m²-9).
<h3>What is an Expression?</h3>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Given the expression 35m²-63, which can be written as,
Taking 7 as common from both the terms,
Hence, the expression that is equivalent to 35m²-63 is 7(5m²-9).

we know that
Every difference of squares problem can be factored as follows:
If the polynomial represent a difference of squares every number must be a <u>perfect square</u> (Remember that a number is a perfect square if its square root is an integer.)
<em><u>Verify each case</u></em>
case 1) we have
In this case both numbers are perfect square
so
therefore
The polynomial represent a difference of squares
case 2) we have
In this case 8 is not a perfect square
therefore
The polynomial not represent a difference of squares
case 3) we have
In this case both numbers are perfect square
but is a sum of squares
therefore
The polynomial not represent a difference of squares
case 4) we have
In this case 2 is not a perfect square
therefore
The polynomial not represent a difference of squares
