I believe you have to multiply
Answer:
B
Step-by-step explanation:
The question said the person bought a shirt which means 1 and 3 pairs of pants which means multiple but we don’t know how many so we substitute that ? for a x so 15 + 3x =117
In the number 54, 625 from left to right:
5 represents 5,
2 represents 20
6 represents 600
4 represents 4000
5 represents 50,000
so
<span>
54,625=50,000+4,000+600+20+5=5*10,000+4*1000+6*100+2*10+5
another way we can write this number is </span>

Answer:
i) 5*10,000+4*1000+6*100+2*10+5
ii)

2 ways, which are essentially the same thing.
We can multiple this binomial and this trinomial to find an equivalent expression.
(x + 4)(3x^2 + 2x)
3x^3 + 2x^2 + 12x^2 + 8x
Combine like terms.
3x^3 + 14x^2 + 8x is the equivalent polynomial.
Answer:
120
