Answer:

f(5)=10 so 10 is your answer.

It will be easier if we wrote some terms to help us predict the nature of the sequence
f(1)=18,f(2)=18-2=16,f(3)=16-2=14,f(4)=14-2=12f(5)=10
so the nth term will be in the form
f(n)=18-2(n-1)

Answer:

26

Step-by-step explanation:

To evaluate this expression, all we have to do is substitute the given values of the variables into the expression. That is, replace every m in the expression with a 1 and every p in the expression with a 5.

Doing so, we get:

p^{2} +m

=5^{2} +1 (Substitute given values into the expression)

=25+1 (Evaluate exponential term)

=\bf26 (Add)

Hope this helps!

Find the measurement of both complementary angles, if the measurement of the first one is 40° less than the measurement of the o
netineya [11]
90 - 40 = 50

Complementary angles add up to 90 degrees.

If one angle is 40 degrees less than the other, you just put it into an equation where 40 is subtracted from 90.

The answer would then be 50 degrees.

Greatest common factor. Can someone please explain
fiasKO [112]
Let's say you have 10 and 15

You can divide both of them by 5

10/5=2
15/5=3

The greatest common factor is 5, because it is the highest number you can divide both numbers by, I hope this helps

Using the following image, solve for FG.
Elza [17]

Step-by-step explanation:

x+x-7=11

2x+7=11

2x=18

2x/2=18/2 = x=9

9-7=2

So, FG=2

3x + x - 13 + 4x =12
GREYUIT [131]
 <span>3x + x - 13 + 4 - 6x =12  

Combine like terms....

- 2x - 9 =12 

Add 9  to both sides....

-2x = 21

Divide both sides by -2 to get x by its self....

x = -21/2</span>
