Question

Rewrite the expression in standard form.

A. (7g - 1)
B. (49g - 7)
C. (7 - g)
D. (7 - 49g)

Answer 1

To rewrite an expression in standard form, the terms should be arranged in order of decreasing powers of the variable. Options C and D need to be rearranged to be in standard form.

Step-by-step explanation:

To rewrite an expression in standard form, we need to arrange the terms in order of decreasing powers of the variable. In this case, the standard form means that the variable should be in front of the numerical coefficient. Let's take a look at each expression:

1. A. (7g - 1) -> This expression is already in standard form.
2. B. (49g - 7) -> This expression is also already in standard form.
3. C. (7 - g) -> To rewrite the expression in standard form, we need to rearrange it as (-g + 7).
4. D. (7 - 49g) -> To rewrite the expression in standard form, we need to rearrange it as (-49g + 7).

Therefore, the corrected expressions in standard form are: A. (7g - 1), B. (49g - 7), C. (-g + 7), and D. (-49g + 7).
