Answer:

It's the first one. (m + n - 1) sqrt p

Step-by-step explanation:

We can combine m sqrt p and n sqrt p, resulting in m + n, and combine - sqrt p to become (m + n - 1)sqrt p

Multiply.Express your answer in standard form.(3 points)(x² -4x + 3)(-3x²+ 7x –1)

bija089 [108]

Answer:

-3x^{4} + 19x^{3} - 38x^{2} + 25x - 3

Step-by-step explanation:

1) distribute x² into (-3x² + 7x - 1) to get: -3x^{4} + 7x³ - x²

2) distribute -4x into (-3x² + 7x - 1) to get: 12x³ - 28x + 4x

3) distribute 3 into (-3x² + 7x - 1) to get: -9x² + 21x - 3

4) combine all the answers together into one equation:

-3x^{4} + 7x³ - x² + 12x³ - 28x² + 4x - 9x² + 21x - 3

5) combine like terms:

7x³ + 12x³ = 19x³

-x² + -28x² + -9x² = -38x²

4x + 21x = 25x

6) combine answers together into one equation:

-3x^{4} + 19x³ - 38x² + 25x - 3

Answer:

D. 4/25

Step-by-step explanation:

If you add up all the number of times they picked up a balloon (50 times because 22 + 7 + 8 + 13 = 50) and how many times the orange balloon was chosen (8) then you will get 8/50 and 8/50 simplified is 4/25.

I NEED HELP WITH NUMBER 6 AND 7! I WILL MARK YOU AS BRAINLIEST IF YOU ANSWER CORRECTLY! PLZ AND TY! :D

Shtirlitz [24]

Answer/Step-by-step explanation:

6. To know who cycled faster between Sam and Bobby, find the constant of proportionality of both of them. The person with the least value of constant of proportionality is the fastest.

Constant of proportionality for Sam = $\frac{distance (y)}{time (x)} = \frac{20}{2} = 10 mph$

Constant of proportionality for Bobby:

Use (0, 0) and (2, 18) to find the constant of proportionality, which is:

$m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{18 - 0}{2 - 0} = \frac{18}{2} = 9 mph$ .

Bobby's unit rate/constant of proportionality is smaller than Sam's.

So, Bobby cycled faster.

7. y = 15x is given as representing the amount of Pauli's Pizzeria Pizza.

15 in the equation is the slope/constant of proportionality, which represents the cost of a unit of pizza.

From the graph, the unit rate/constant of proportionality of Leo's Pizzeria Pizza can be calculated as, y/x.

Using (2, 24), we have 24/2 = 12

This means Leo's Pizzeria cost $12 per pizza.

Therefore:

Pauli's Pizzeria takes in $15 per pizza

Leo's Pizzeria takes in $12 per pizza

Pauli's Pizzeria takes in more money per pizza.
