Answer:

3m - 8

Step-by-step explanation:

Step by Step:

Equation= 6m³ - 16m² + 15m - 40/ 2m² + 5

Factor out 2m² from 6m³ - 16m²:

Factor out 5 from expression:

2m²(3m - 8) + 5(3m - 8)/2m² + 5

Factor out 3m - 8:

(3m - 8)(2m² + 5)/2m² + 5

Rude the fraction with 2m² + 5:

3m - 8 is the answer

I hope this helped!

The answer is the mean is 8. The range is equal to the largest number, 10 minus the smallest number, 5. It equals 5, so d is wrong. The mean is all of the values added together, 80, divided by the number of values, 10. So, 8. The median is the middle which is between 7 and 8, so 7.5. Five has no dots.

Questions:

My name is Ann [436]

The solution to the expressions given are;

9 -9t/ 12 - 5t

a. 20/ 169

b. -170/ 169

c. 386/ 169

d. -10/ 169

<h3>How to solve the expressions</h3>

Given:

$\frac{9 - 19t}{12 - 5t}$

We can see that both variables in the numerator and denominator have no common factor, thus cannot be factorized further

a. $\frac{203}{169} - \frac{183}{169}$

First, let's find the lowest common multiple

LCM = 169

= $\frac{203 - 183}{169}$

= $\frac{20}{169}$

= 20/ 169

b. $\frac{13}{119} - \frac{183}{119}$

The lowest common multiple is 119

= $\frac{13 - 183}{119}$

substract the numerator

= - 170/ 119

c. $\frac{203}{169} - \frac{183}{169}$

The lowest common multiple is 169

= $\frac{203 + 183}{169}$

= 386/ 169

d. $\frac{9}{169}- \frac{19}{169}$

The lowest common multiple is 169

= $\frac{9 - 19}{169}$

= - 10/ 169

Thus, we have the solutions to be 9 -9t/ 12 - 5t, 20/ 169, -170/ 169, 386/ 169, -10/ 169 respectively.

Answer:

5y + 7

Step-by-step explanation:

Given:

Seeds planted in one garden = y vegetable seeds

Seeds planted in another garden = 4y + 7 vegetable seeds

To Find:

The number of seeds Val is going to plant = ?

Solution:

Let the total number of seeds that Val is going to plant be x.

Then

x = number of seeds planted in garden one + number of seeds planted in the other garden

Now substitute the values, we get

x = y + (4y+7)

x = 5y + 7

Select the two binomials that are factors of this trinomial x^20 - x - 20

Mashcka [7]

Answer:

$(x-5)(x+4)$

Step-by-step explanation:

To factor the equation, break it into two binomials which multiply to make the equation. To write these binomials (x+a)(x+b), find factors which multiply to -20 and add to -1 for a and b.

20: 1, 2, 4, 5, 10, 20

-5+4 = -1

$x^2-x-20 = (x-5)(x+4)$
