Step-by-step explanation:
When two statements are connected with an 'and,' you have a conjunction.
For conjunctions, both statements must be true for the compound statement to be true.
When the connector between two statements is "or," you have a disjunction. In this case, only one statement in the compound statement needs to be true for the entire compound statement to be true.

The student is wrong.
Step-by-step explanation:
To divide exponents (or powers) with the same base, subtract the exponents. In the second step, the wrong result is calculated.
First, plug in 448 for y:
448=7x+294

154=7x
Divide both sides by 7:
22=x
Refine:
x=22
The answer is D)22
