Find the two numbers that multiply to get 35 and subtract to get 2. The two numbers should be 5 & 7.

⟶ [tex] \tt{5 {x}^{2} - (7 - 5)x - 7}[/tex]

Distribute x through the parentheses

⟶ [tex] \tt{5 {x}^{2} - 7x + 5x - 7}[/tex]

⟶ [tex] \tt{ \underbrace{5 {x}^{2} - 7x } \: + \underbrace{5x - 7}}[/tex]

⟶ [tex] \tt{x(5x - 7) + 1(5x - 7)}[/tex]

⟶ [tex] \tt{(x + 1)(5x - 7)}[/tex]

The cost of a sweater at a clothing store was $35. The sweater went on sale at a discount of 20% off the original price. What is the sale price of the sweater?

Answers

The answer is 28$ :))

Answer:

$28

Step-by-step explanation:

First, we have to find 20% of 35.

We can do that by multiplying 0.20 by 35. (0.20 x 35)

After multiplying them, we get a product of $7.

Since the sweater went on sale and they took 20% off of the original price, we have to subtract $7 from the original price of $35. (35 - 7)

We can solve that to get us the discounted price of $28

Traveling 10 meters in 1/3 of a second how fast was it going

Answers

Answer:

I guess he was traveling 30 meters every second.

(Which is pretty slow to be honest)

Step-by-step explanation:

This question doesn't really make sense since it says it right there he traveled 10 meters in 1/3 of a second. But I'm guessing that you want to find out how many meters per second.

Since 1/3 multiplied by 3 = 1

Then 10 multiplied by 3 = 30.

So, he traveled 30 meters every second.

Step-by-step explanation:

The perimeter is the sum of the 4 sides, that is

x + x + 274 + x + 27 + x + 74 = 3279, that is

4x + 375 = 3279 ( subtract 375 from both sides )

4x = 2904 ( divide both sides by 4 )

x = 726
