-3 subtract the perenthesis (-1) equal to -2
Answer:
yes they are equivalent. if you simplify -21/-56 by dividing it by 3 you will get -7/-21 which equals to 7/21
The image is really unclear but I will assume that the number of teams given = 66
and the formula is

plug in the number of teams

multiply both sides by two

subtract 132 from both sides and factor
t = 12
Answer:
I love algebra anyways
The ans is x=3 steps is in the picture with the ans
(hope this helps can i plz have brainlist :D hehe)
Step-by-step explanation:
Answer:
x = 2 x = -6
Step-by-step explanation:
2 (x+2) ^2-4=28
Add 4 to each side
2 (x+2) ^2-4+4=28+4
2 (x+2) ^2= 32
Divide by 2
2/2 (x+2) ^2=32/2
(x+2)^2 = 16
Take the square root of each side
sqrt((x+2)^2) =±sqrt( 16)
x+2 = ±4
Subtract 2 from each side
x+2-2 = -2±4
x = -2±4
x = -2+4 and x = -2-4
x = 2 x = -6
