Answer:a
Step-by-step explanation:
Answer:
Step-by-step explanation:
must gain 10 yards
they lost 24 yards
gained 4
-24 + 4 = -20
they lost 10 more
- 20 -10 = -30
x + -30 = 10
x = 10 + 30
x = 40 yards
Divide both sides by 2
b^2 = 48
b = +/- sqrt 48
= +/- 6.93 to nearest hundredth
"For any three consecutive numbers": x,y,z:
x
y=x+1
z=x+2
"prove algebraically that the largest number and the smallest number are factors"
x*z=
"of the number that is one less than the square of the middle number"
=y²-1
x*z=y²-1
x*(x+2)=(x+1)²-1
x²+2x=x²+2x+1-1
x²+2x=x²+2x
both sides of the equation are the same, so the statement is correct
A. 6 because it is in the middle of the data.
