B :step 2 she didnt collect all the like terms and calculate
Step-by-step explanation:
first rewrite remove all ( )Parentheses
2nd collect all like terms and calculate
a^4 + 7a -16 -12^a^3 + 5a -3

so she skipped the second step
Answer:
x=3 and y=2
Step-by-step explanation:
The pythagorean triples are generated by two integrers x and y that can be found by solving the following system of equations:
Solve the system of equations, and we get that the solution is x=3 and y=2.
Therefore, the combination of integrers that ca be used to generate the pythagorea triple are: x=3 and y=2
Real numbers are all rational numbers such as -7 and 4/3 and all irrational numbers. Real numbers are mainly used in counting and also in measurement which is used a lot in real world situations. These numbers help is quantify in the real world.
Hope this helps! Can you give me a brainliest please? I need them badly !

Tom spent more on tax ($1.54 vs his cousin's $0.72)
Step-by-step explanation:
Tom: $22 x 1.07 = $23.54
tax spent = 22 x 0.07 = $1.54
Cousin: $18 x 1.04 = $18.72
tax spent = 18 x 0.04 = $0.72
Total= $23.54 + $18.72 = $42.26
