First simplify the expression as much as possible.
2x - x + 5
2x - x = x
x + 5
There are two terms, x and 5. expressions that have two terms are known as binomials
binomials should be your answer.
hope this helps

Answer:
-13a^2 + 170ab - 13b^2.
Step-by-step explanation:
1. 36(a+b)^2 - 49(a-b)^2
This is the difference of 2 squares: a^2 - b^2 = (a + b)(a - b).
36(a+b)^2 - 49(a-b)^2
= (6(a + b) + 7(a - b))( 6(a + b) - 7(a - b))
= (6a + 7a + 6b - 7b)( 6a - 7a + 6b + 7b)
= (13a - b)(-a + 13b)
If you require the expansion of this it is:
-13a^2 + 170ab - 13b^2.
V = 297 for a square pyramid, I hope its right..
Answer:
"simplify"
Step-by-step explanation:
The notion of <em>simplifying</em> an expression depends on the expression. For the one offered as an example, the simplification steps required are eliminating parentheses and combining like terms.
Other possible simplification steps include combining fractions, reducing fractions, and rationalizing denominators (eliminating surds or complex numbers).
It appears the vocabulary word that is desired in the blank is <u>simplify</u>.
