It's a possibility. What's it worth to you, and what's your question ?
For this case we have a factorized quadratic equation. We equal each factor to zero and thus find the roots:
Subtracting 5 from both sides we have:
Thus, the first solution of the equation is:
On the other hand we have:
Adding 3 to both sides:
Thus, the second solution of the equation is:
Answer:
The solutions of the equation are:
Answer:
Yes, the triangles are similar by SAS
Step-by-step explanation:
Looking at the picture, we see that there are two triangles with side lengths of different sides. We can deduce that the scale factor is 1 2/3, because 8 divided by 4.8 is 1 2/3, and 10 divided by 6 is the same. Now that we have clarified that the triangles share the same scale factor, we notice that the angle is also the same, as mentioned in the picture. This leads us to say that the triangles are similar by the SAS similarity theorem (Side, Angle, Side). I hope this helped and please don't hesitate to reach out with more questions!
Answer:
x = 5
Step-by-step explanation:
5(2x-5) +10x = 75
10x -25 +10x = 75
20x - 25 = 75
20x = 100
x = 5
Answer:
11 speakers
Step-by-step explanation:
2 3/4 ÷ 1/4
11/4 ÷ 1/4
11/4 x 4/1 = 44/4 = 11
