Simplify the sum.<br> (4u3 + 4u2 + 2) + (6u3 – 2u + 8)
Elan Coil [88]

Answer:

10u^{3}+4u^{2}-2u+10 or 2(5u^{3}+2u^{2}-u+5)

Step-by-step explanation:

we have

(4u^{3}+4u^{2} +2)+(6u^{3}-2u+8)

step 1

Group terms that contain the same variable

(4u^{3}+6u^{3})+(4u^{2})+(-2u)+(2+8)

step 2

Combine like terms

(10u^{3})+(4u^{2})+(-2u)+(10)

step 3

Eliminate parenthesis

10u^{3}+4u^{2}-2u+10

step 4

Factor the number 2

2(5u^{3}+2u^{2}-u+5)

Tpy6a [65]

Answer:

30,240 ways,  if I am restricted to using A, B, and C for letters

Step-by-step explanation:

This uses Combinatorics from Discrete Math.

so.

3 letters  and 4 digits.

26 letters from alphabet, but you want to choose first letters.  no repeats...

Does this mean only letters A, B, and C ?

digits from 10 digits...

I imagine  7 empty slots , and the number of ways they occur together is by the product of the number of choices each box has.

3*2*1  *  10*9*8*7 = 6  * 5040  = 30,240 ways

What is the value of 6 in 4.769
mixer [17]
<span>The <u>correct answer</u> is:

6/100.

Explanation<span>:

We look at place value to answer this. The digit in front of the decimal is the ones; directly after the decimal we have the tenths; behind this we have the hundredths; and behind this we have the thousandths.

6 is two places behind the decimal; this is the hundredths place. This means it is six hundredths, or 6/100.</span></span>
