Solve for x (x+7)^2-49=0 find the smaller and larger x smaller x= larger x=

x = -14  and x=0

Step-by-step explanation:

(x+7)^2-49=0

Add 49 to both sides

(x+7)^2-49+49=0+49

(x+7)^2 = 49

Take the square root of each side

sqrt((x+7)^2) = ±sqrt(49)

(x+7) = ±sqrt(49)

x+7 = ±7

Subtract 7 from each side to isolate x

x+7-7 = -7±7

x =  -7±7

x = -7+7    and x =  -7-7

x = 0  and x=-14

the third fish weighs 1 2/5 pounds

Step-by-step explanation:

find common denominator for fraction which would be 15

fish 1=2 5/15

fish 2=1 9/15

fish1/2= 3 14/15

5 5/15- 3 14/15 =1 6/15

simplify to 1 2/5
