What is the value of x?<br><br> What is the value of y?
Rudik [331]

Answer:

Y= 20

X= 25

Step-by-step explanation:

The angles of a triangle have to equal 180

So

80+60 = 140

180 - 140 = 40

40/2 = 20

Y = 20

The angles of a linear line split equal 180

So

2y is one side of it which we learned Y = 20 which makes that side 40

To find the other side just guess and check

6(25) = 150

150 - 10 = 140

So the 2y = 40 and the (6x-10) = 140

So yea boom done

What are the factors of the expression x^2+x-20?
tatyana61 [14]

Answer:

(x-4)(x+5)

Step-by-step explanation:

Find 2 numbers knowing sum (1) and product (-20). To find them, factor pairs of (-20) --> (-2,10) (-4,5). This sum is 1=b. Then, these 2 numbers are: - 4 and 5. Y=(x-4) (x+5). Hope this helped :)

Which student correctly used guess and check to determine the unknown number?
Alenkasestr [34]
<h2>Explanation:</h2><h2></h2>

Hello! Remember you need to write complete questions in order to get good and exact answers. Here we know nothing about the students so I can only help you providing the correct steps to find <em>the product of a number and eight is 104:</em>

<em />

Let that number be n, then the statement can be written in a mathematical language as follows:

n\times 8=104 \\ \\ \\ \text{Dividing both sides by 8:} \\ \\ \frac{n\times 8}{8}=\frac{104}{8} \\ \\ \boxed{n=13}

Finally, <em>the unknown number is 13</em>
