What are the variable terms in the expression? 6x^2 + 3xy + 4z

2 answers:

7 0

All three of them are variable terms because they all contain a variable and a term would be the whole set of numbers that are separated by the addition signs. in this one the variable terms are 6x^2, 3xy, and 4z<span />

Answer:

$6x^2,3xy,4z$

Step-by-step explanation:

We are given that an expression

$6x^2+3xy+4z$

We have to find the variable terms in the given expression.

Variable term: The term which contains variable is called variable term.

Constant term:The term which does not contain variable is called constant term.

To find the variable terms we will find the terms which contains variable.

We can see that in the given expression

There are three terms which contain variables.

Hence, the variable terms are

$6x^2,3xy,4z$

PLZ HELP!<br> find the value of f(-2) for the function f(x)=4x+10<br> Show work please

natita [175]

Answer:

f(-2) = +2

Step-by-step explanation:

Let x = -2

So,

f(x) = 4x + 10

Substituting the value of x gives ,

f(-2) = 4 × (-2) + 10 = 10 - 8 = 2

Find the ratio a:b, if 2a−b/6 = b/3

Tom [10]

Answer:

a:b = 2

Step-by-step explanation:

Here we need to operate with terms in order to arrive to a ratio a:b (or a/b).

We have:

2a−b/6 = b/3

Lets sum b/6 in both sides:

2a−b/6 + b/6 = b/3 + b/6

2a = b/3 + b/6

Now, we can multiply and divide b/3 by 2 to make a 6 appear on the denominator and sum it with b/6, this is, use common denominator:

2a = b/3*(2/2) + b/6

2a = 2b/6 + b/6

2a = 3b/6

2a = b/2, as 3/6 = 1/2

Now lets divide both sides by b to make an a/b appear:

2a/b = (b/2)/b

2a/b = 1/2

Finally, multiply both sides by (1/2) or divide by 2:

(2a/b)/2 = 2

a/b = 2

This is, a is twice as b. If b is 1 so a is 2; if b is 45 so a is 90, and so on.

If the circumference of a circle measures 12π cm, what is the area of the circle in terms of π?

frez [133]

So the formula for the circumference of a circle is π x diameter
Since we know the the circumference already, we just divide that by π:

12π / π = 12

Now we halve the diameter to get the radius:
12 / 2 = 6

The area of a circle is π x radius²
So the area is:

·π x 6² = 36π· (or 113 not in terms of π)
