Answer:

The correct option is b.

Step-by-step explanation:

We have to find the product of \frac{2a-7}{a}  and  \frac{3a^2}{2a^2-11a+14}.

Multiply both terms.

\frac{2a-7}{a}\times \frac{3a^2}{2a^2-11a+14}

Cancel out the common factor a from numerator and denominator.

\frac{2a-7}{1}\times \frac{3a}{2a^2-7a-4a+14}

\frac{2a-7}{1}\times \frac{3a}{a(2a-7)-2(2a-7)}

\frac{2a-7}{1}\times \frac{3a}{(2a-7)(a-2)}

Cancel out the common factor (2a-7) from numerator and denominator.

\frac{1}{1}\times \frac{3a}{a-2}

\frac{3a}{a-2}

Therefore, the correct option is b.

Andre and Elena are each saving money. Andre starts with $100 in his savings account and adds $5 per week. Elena starts with $10
Tomtit [17]

Answer:

Andre have more money after 4 weeks and after 6 week they have same amount of money.

Step-by-step explanation:

When Andre =100 then Elena =10.

After 4 week,

Andre = 100+(5*4)=100+20=120

In this time Elena = 10+(20*4) =10+80 = 90

After more 2months Andre have more 5+5=10

Then his total balance will be 120+10=130.

Than Elena after 2 week have 20+20=40.

Then her total balance will be 90+40=130.

That's mean 4 weeks+ extra 2 weeks total 6 weeks
