Why can you not combine the 8a2 and 8a?

Answers

Answer:

you can't add or subtract numbers that don't have the same variable or the same exponent

Answer:

You cannot combine the terms [tex]8a^2[/tex] and [tex]8a[/tex] because they are not like terms, which are terms that consist of both the same power, and the same variable. Seen with the two terms given, they both share the same variable ([tex]a[/tex]), but not the same power ([tex]2[/tex]).

Briefly explain how to convert a fraction to its decimal
form.

Answers

Answer:

you just divide

Step-by-step explanation:

Just divide the top of the fraction by the bottom, and read off the answer!

Answer: So what my teacher always told me to do was act like a fraction was a tree. The tree always falls to the left which then outs the fraction as a division problem. You solve the division problem

Step-by-step explanation:

Ok so for example, lets use [tex]\frac{1}{2}[/tex]. Drawing it as a tree it then falls to the left. Therefore it becomes 1 ÷ 2. So 2 can not go into one therefore you need to put a decimal point at the top and add a zero behind the 1 under the bar. The 1 then becomes a 10, therefore 2 can go into 10 5 times. However the answer is not 5. You have to remember to bring the decimal point that you placed before the 5. In conclusion hte answer is .5 . This may be confusing because I am not able to include any photos but hopefully you'll get the point.

Find the Distance between the points (-6,5)and(8, -3)


Answers

Answer:

[tex]d=16.1245[/tex]

Step-by-step explanation:

Distance Formula: [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Simply plug in your 2 coordinates into the formula to find distance d:

[tex]d=\sqrt{(8-(-6))^2+(-3-5)^2}[/tex]

[tex]d=\sqrt{(8+6)^2+(-8)^2}[/tex]

[tex]d=\sqrt{(14)^2+64}[/tex]

[tex]d=\sqrt{196+64}[/tex]

[tex]d=\sqrt{260}[/tex]

[tex]d=16.1245[/tex]

Arson destroys neighborhoods as surely as mass bombings. Only a few people commit the crime, but all residents must suffer the consequences. How could it be otherwise, given the nature of the problem, with its tangle of social and economic issues? Decaying buildings are torched by their owners to collect insurance money. This is a despicable crime and ought to be vigorously investigated and punished. Most arsonists escape punishment. Burnt-out structures are, in turn, a haven for gangs and drug traffickers, who cause even more arson. Once several blocks have been gutted, a kind of collective hopelessness grips those who cant afford to move. The young may continue to set fires from hatred or from despair of ever escaping their crumbling prison. The old and sick become the prey of robbery or random violence, their final years drawn into a whirlpool of fear.
