Answer:

x= -3+√2 or x= -3-√2   ( answer : A  and B )

Step-by-step explanation:

hello :

x²+6x+9 = (x+3)².....identity

x²+6x+9 =2  means : (x+3)²=2

so : (x+3 = √2) or  (x+3 = - √2)

so two solutions :

x= -3+√2 or x= -3-√2

the variable z is directly proportional to x. when x is 6, z has the value 18. what is the value of z when x = 10 the variable z
nikklg [1K]
Z\alpha x
Z=kX
When x=6, z=18,
Finding value of z,
18=k*6
k=3
Z=3X
when x=10,
Z=3*10
Z=30

Part B;
Z\alpha  \frac{1}{x}
z=\frac{a}{x}
Where x is a constant of proportionality,
when x=3, z=2
2=\frac{a}{3}
a=3*2
a=6
When x is 13,
Z=\frac{6}{13}

You are buying lawn seed for the the football field a 10 pound bag of lawn seed covers 2000 square feet.
Masja [62]

A football field is 120 yards long (100 yards playing field plus 2 end zones 10 yards each) by 53 1/3 yards wide.

1 yard = 3 feet.

120 yards x 3 feet per yard = 360 feet

53 1/3 yards x 3 = 160 feet.

The area of the football fields is 360 x 160 = 57,600 square feet.

1 bag covers 2000 square feet:

57,600 / 2,000 = 28.8 bags, round up to 29 bags are needed.

1 bag cost $27.79.

29 bags x $27.79 = $805.91 total cost.

PLZ HELP MEH WITH MATH XD
irina [24]
To add any fraction You need to make sure that the denominator of the fractions are same. ( denominator in your sum is 19 )

10/19 + 3/19 ( we have the same denominator )
we can also write this problem like
( 10 + 3 ) / 19  { add the numerators together }
13 / 19

So correct option is B.

hope this helped..  :)
