You have to switch the sign of all terms within the parentheses. For example,
-(a - b + c - d)
becomes
-a + b - c + d
you turn everything inside the prenthises positive or negative
A "+" before parentheses means + 1 times everything inside, so +(a+b-c) means +a+b-c
It is: 3n-21+4n+8 = 7n-13 simplified
As there are no parentheses then the expression stated can be simplified as follows :- 7x - 4x - 9 = 3x - 9 If the parentheses were placed (7x - 4x) - 9 then the result would be the same. If the parentheses were placed 7x - (4x - 9) = 7x - 4x + 9 = 3x + 9.
A spatula would be used to remove 0.25 grams of a solid material from a reagent bottle.
2-(-1)= 2+1= 3 When a parenthesis is preceded by a minus sign, remove the parentheses and the minus sign before the parentheses and change the sign of each term within the parentheses. When a parenthesis (-1) is preceded by a minus sign, -(-1) remove the parentheses ( ) and the - sign before the parentheses and change the sign of each term -1 within the parentheses +1
You can remove parenthesis or bracket by multiplying the number outside, with the number inside the bracket.
No, prokaryotes do not remove introns during gene expression.
Remove all the algebraic letters and their powers and what you are left with is the coefficient.
you turn everything inside the prenthises positive or negative
Below the picture there will be your name and in parenthesis it will say "Remove tag". If you press that than the tagged photo will not appear on your pictures anymore.

Yes.
You change the sign of each of the terms inside the parentheses. For example:- (a - b + c)becomes:-a + b - c
A "+" before parentheses means + 1 times everything inside, so +(a+b-c) means +a+b-c
Algebra tiles are physical or virtual manipulatives that represent variables and constants, making it easier to visualize and perform operations with algebraic expressions. To add or subtract expressions, you can use tiles to represent each term: for example, use a specific tile for each variable (e.g., x) and constant (e.g., 1). To add, combine the tiles by grouping like terms, while for subtraction, you remove the tiles representing the terms being subtracted. This visual method helps students understand the concept of combining like terms and simplifying expressions.
