How do you solve 13y^2-5yx-8x^2

Answers

Answer 1

Answer:

Answer:

(13y+8)(y-x)

Step-by-step explanation:

13 $y^(2)$ - 5yx -8 $x^(2)$

we can solve above equation by using splitting the middle term

we can factorize it by splitting the middle term

13 $y^(2)$ - 5yx -8 $x^(2)$

=13 $y^(2)$ - 13yx+8yx -8 $x^(2)$

=13y(y-x)+8x(y-x)

=(13y+8)(y-x)

There are the two factors because the degree of the polynomial is 2

Hence, the correct answer is (13y+8)(y-x)

Answer 2

Answer: Step 1 :Simplify 13y2-5yx - 23x2
1.1 Factoring 13y2 - 5yx - 8x2 Try to factor this multi-variable trinomial using trial and error Found a factorization : (y - x)•(13y + 8x)
Final result : (y - x) • (13y + 8x)

Answers

First, you should substitute a, b, and c with -3, 9, and 4, so you get 4(-3(2)+9+4)

Next, following PEMDAS, you solve everything in the (,), leaving you with 4(7).

Step-by-step explanation:

Lin rode a bike 20 miles in 150 minutes. If she rode at a constant speed, how far did she ride in 15 minutes? How long did it take her to ride 6 miles? How fast did she ride in miles per hour?

Answers

Hey there! :)

Answer:

First part: 2 miles.

Second part: 45 minutes

Third part: 8 mph.

Step-by-step explanation:

We can divide this question into 3 parts.

Begin by solving for the distance traveled after 15 minutes by creating a ratio:

$(20 mi)/(150min) = (x)/(15 min)$

Cross multiply:

20 · 15 = 150 · x

300 = 150x

300/150 = 150x/150

x = 2 miles.

2nd part: How long it took her to ride 6 miles.

Set up another ratio similar to the one used before:

$(20 mi)/(150min) = (6mi)/(x min)$

Cross multiply:

20 · x = 6 · 150

20x = 900

20x/20 = 900/20

x = 45 minutes.

3rd part:

For this part, we will need to convert from minutes to hours.

$(20 mi)/(150 min)* (60 min)/(1 hr) = (1200mi)/(150hr) = 8 mi/h$

Therefore, her speed is 8 mph.
