Answer:

HOPE THAT MAY HELP YOU :)

Step-by-step explanation:

Equal groups are illustrations of using the same variable.

A word problem that uses equal group is:

Christopher traveled a distance of 5 miles yesterday; he traveled a distance of 4 miles earlier today. Calculate the total distance traveled

The only condition for equal groups is that:

The units or variable must be the same

For instance:

Add 5 miles and 4 miles ----- This represents distance

Remove 2 liters from 7 liters --- This represents volume

Add 5 hours and quarter of an hour -- This represents time

And so on.

Which expression is equivalent to Left-bracket log 9 + one-half log x + log (x cubed + 4) Right-bracket minus log 6? log StartFr

dybincka [34]

Answer:

$\log{\dfrac{3\sqrt{x}(x^3+4)}{2}}$

Step-by-step explanation:

$\log{9}+\dfrac{1}{2}\log{x}+\log{(x^3+4)}-\log{6}=\log{\left(\dfrac{9x^{\frac{1}{2}}(x^3+4)}{6}\right)}\\\\=\boxed{\log{\dfrac{3\sqrt{x}(x^3+4)}{2}}}\qquad\text{matches choice A}$

The applicable rules of logarithms are ...

log(ab) = log(a) +log(b)

log(a/b) = log(a) -log(b)

log(a^b) = b·log(a)

Xander needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items.

Aleksandr [31]

Answer:

c ≥ 56 is the REQUIRED INEQUALITY.

Step-by-step explanation:

Here, the given question is INCOMPLETE.

Xander needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items. Choose the inequality and solution to represent the number of cans, c, that Xander must still collect.

Now, here:

The number of cans Xander needed to collect = At least 120

The number of items already collected = 64

c: the number of cans, c, that Xander must still collect.

Now, the number of cans to be collected - Cans already collected

= 120 - 64 = 56

So, the number of can he must collect to make a TOTAL OF AT LEAST 120 cans = 56 cans

⇒ The number of cans to be collected ≥ 56 cans

⇒c ≥ 56 cans

or, c ≥ 56 is the REQUIRED INEQUALITY.
