Answer:

17

Step-by-step explanation:

Given:

The given expression is.

3x+2

We need to solve the given expression for x = 5.

Solution:

Rewrite the expression as.

f(x)=3x+2

Substitute x = 5 in above expression.

f(5)=3(5)+2

f(5)=3\times 5 + 2

Now we multiply 5 with 3.

f(5)=15+2

Now we add right side terms.

f(5)=17

Therefore, The correct value of given expression is 3x+2=17 for x=5.

seropon [69]

Step-by-step explanation:

arithmetic sequence.

an = an-1 + c = a1 + (n-1)c

c is in our case 2 (every new shape has 2 more vertices).

we have a a1 = 3.

an = 3 + 2(n-1)

so,

a21 = 3 + 2(20) = 3 + 40 = 43

the 21st shadow will have 43 vertices.

What inverse operations are used to solve the equation? 2x + 2 = 10
mestny [16]

Answer:

C

Step-by-step explanation:

You basically have to get X by itself. So you subtract 2 to both sides giving you 2X = 8. Then you divide 2 to both sides give you X = 4.
