Question 264355: Please can anyone help me I am lost.
17. On three consecutive passes, a football team gains 9 yards, loses 16 yards, and gains 42 yards. What number represents the total net yardage?
The total net yardage is _______yds.
18. Use the distributive property to help you solve the equation.
3(w-3)=-9
w=______
19. Find the domain of the function.
g(x)= 6/8-9x
a. {x|x is a real number and x >= 8/9} that is greater than or equal too
b. {x|x is a real number and x =/ 0} the = should have the / thru it.
c. {x|x is a real number and x=/ 8/9}
d. {x|x is a real number and x =/ 6}
21. Evaluate
r+s/ 8 for r= 40 and s=16
r+s/8= _______
22. Find the domain of the function.
p(x)= x to the 2 power - 2x +7
A. {x|x is a real number and x =/0}
b. {x|x is a real number and x =/7}
c. {x|x is a real number}
d. {x|x is a real number and x>0}
24. Solve using the multiplication principle. Dont forget to perform a check.
12x= -84
The solution is x= _______?
I thank you in advance for you knowledge and generousity in helping people like me who are mathmatically challenged.

You can put this solution on YOUR website! 17. On three consecutive passes, a football team gains 9 yards, loses 16 yards, and gains 42 yards. What number represents the total net yardage?
The total net yardage is _______yds.
9-16+42 => -5+42 => 37yards
18. Use the distributive property to help you solve the equation.
3(w-3)=-9
w=______
(3)w -(3)3=-9 => 3w-9=-9 => 3w=0 => w=0,
check: 3(0-3)=-9 => 3(-3)=-9 => -9=-9
21. Evaluate
r+s/ 8 for r= 40 and s=16
r+s/8= _______
(40+16)/8 => 56/8=7
24. Solve using the multiplication principle. Dont forget to perform a check.
12x= -84
The solution is x= _______?
-84/12=x => -7=x, 12(-7)=-84 => -84=-84
