Answer:

-1 and -3

(n+7)(n-8)

Step-by-step explanation:

1. Find the Zeros

f(x)=x^{2} +4x+3

f(x)=\left(x+1\right)\left(x+3\right)

x+1=0\\x=-1\\x+3=0\\x=-3

2. Factoring Trinomials

f(x)=n^{2} -n-56

f(x)=\left(n+7\right)\left(n-8\right)

n+7=0\\n=-7\\n-8=0\\n=8

85% of the people survey thought the price of the car wash was reasonable. If 164 people thought the cost of the car wash was re
8090 [49]

192 people were survey

Step-by-step explanation:

The given is:

  • 85% of the people survey thought the price of the car wash was reasonable
  • 164 people thought the cost of the car wash was reasonable

We need to find how many people were survey

Assume that x people were survey

∵ There were x people survey

∵ 85% of them thought the price of the car wash was reasonable

∴ The number of the people who thought the price of the car wash

   was reasonable = 85% × x

∵ 85% = \frac{85}{100} = 0.85

∴ The number of the people who thought the price of the car wash

   was reasonable = 0.85 x

∵ 164 people thought the cost of the car wash was reasonable

- Equate 0.85 x and 164

∴ 0.85 x = 164

- Divide both sides by 0.85

∴ x = 192.94

∵ x represents a number of people, then it must be integer

∴ The number of people were survey = 192

192 people were survey

3 were called on Friday.
Then the each of the 3 called 3 others which all equals to 9, since 3*3 is 9.
Now, each of the 9 called 3 others on Sunday which altogether equals 27, since 9*3 is 27. Therefore, the answer is 27.

Every time the word each is used in a math problem, that would mean that you need to multiply something. And that's what happened here

Zak buys 6 gallons of fruit punch. He has coupons for $0.55 off the regular price of
kherson [118]

Answer:

$2.00

Step-by-step explanation:

If Zak is Buying 6 gallons, and he has a coupon for each gallon for $0.55 off, we need to first find how much he saved.

We can do this by calculating $0.55 (or 0.55) multiplied by 6. This answer is 3.30, or $3.30.

Now we add $3.30 to $8.70 to get the normal price for 6 gallons of fruit punch.

3.30 + 8.70 = 12.00, or $12.00

The normal price for 6 gallons of fruit punch is $12.00.

Now, we divide 12 by 6 to get the cost of one single gallon of fruit punch.

12/6 = 2

One gallon of fruit punch costs $2.00

Hope this helps! Have a great rest of your day! :)
