PLS HELP

Answers

Answer 1

Answer:

2z^3 - 5z^2 + 4z - 1

Step-by-step explanation:

(2z - 1)(z^2 – 2z+ 1) =

= 2z^3 - 4z^2 + 2z - z^2 + 2z - 1

= 2z^3 - 5z^2 + 4z - 1

Answer 2

The polynomial in standard form will be 2z³ – 5z² + 4z – 1.

What is polynomial?

A polynomial expression is an algebraic expression with variables and coefficients.

The polynomial is given below.

⇒ (2z – 1)(z² – 2z+ 1)

Then the polynomial in standard form will be

⇒ (2z – 1)(z² – 2z + 1)

⇒ 2z(z² – 2z + 1)  – 1(z² – 2z + 1)

⇒ 2z³ – 4z² + 2z – z² + 2z – 1

⇒ 2z³ – 5z² + 4z – 1

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

Step-by-step explanation:

Alright so this problem is like that other one i did where line RQx2 is equal to line SU

First we set up an equation

x+3=x-2

because line RQ is only 1/2 of line SU we multiple its side by 2 to get the new equation of

x+3=2x-4

step 1 subtract each side by 2x

-1x+3=-4

step 2 subtract each side by 3

-1x=-7

divide each side by -1

x=7

Next we plug in x (7) so 7-2=5

line RQ=5

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.
