Answer:
169
Step-by-step explanation:
Add: 9 + 4 = 13
Exponentiation: the result of step No. 1 ^ 2 = 13 ^ 2 = 169
Divide: 15 / 3 = 5
Subtract: 5 - the result of step No. 3 = 5 - 5 = 0
Add: the result of step No. 2 + the result of step No. 4 = 169 + 0 = 169
Given:
Perimeter of a football field = 920 feet.
The width is 60 feet more than one-third of the length.
To find:
The dimensions of a football field.
Solution:
Let the length of the field be x.
Then, width = 
We know that,




Subtract both sides by 120.


Multiply both sides by 3.

Divide both sides by 8.

Now,




Therefore, the length and width of the football field are 300 feet and 160 feet respectively.
Given: F = {(0, 1), (2, 4), (4, 6), (6, 8)} and G = {(2, 5), (4, 7), (5, 8), (6, 9), (7, 5)} (F + G) (2) =

Answer:
9
Step-by-step explanation:
(F+G)(2)
=F(2)+G(2)
Stop!
F(2) means what is y when x=2 looking at function F.
F(2)=4 since F has the ordered pair (2,4) which says when x=2, y=4.
G(2) means what is y when x=2 looking at function G.
G(2)=5 since G has the ordered pair (2,5) which says when x=2, y=5.
G(2)=5.
Continue!
(F+G)(2)
=F(2)+G(2)
=4+5
=9

For

the value of

is negative, and for

the value is positive which means between

and

there is an x for which the value of

is equal to 0 and therefore there is a solution.
