Step-by-step explanation:
Hello, I assume that you mean
![x^2-5x-36](https://tex.z-dn.net/?f=x%5E2-5x-36)
The product is -36.
![x_1 \text{ and } x_2 \text{ are the two roots, we can write}\\\\(x-x_1)(x-x_2)=x^2-(x_1+x_2)x+x_1\cdot x_2](https://tex.z-dn.net/?f=x_1%20%5Ctext%7B%20and%20%7D%20x_2%20%5Ctext%7B%20are%20the%20two%20roots%2C%20we%20can%20write%7D%5C%5C%5C%5C%28x-x_1%29%28x-x_2%29%3Dx%5E2-%28x_1%2Bx_2%29x%2Bx_1%5Ccdot%20x_2)
So in this example, it means that the sum is 5 and the product is -36.
Thank you
Answer:
0.25
Step-by-step explanation:
Prime outcomes on a die: 2,3,5
P(prime) = 3/6 = 1/2
Even outcom: 2,4,6
P(even) = 3/6 = 1/2
P(prime & even)
= P(prime) × P(even)
= ½ × ½
= ¼ or 0.25
Answer:
C
Step-by-step explanation:
The first equation has to be the ratio of raisins to sunflower seeds. If r is raisins and p is sunflower seeds and there are 3 times as many raisins as sunflower seeds then the first equation must be 3r=p
The second equation should model the prices properly. Raisins are 1.5 per pound and sunflower seeds are 4 per pound, because of this we should have 1.5r (r being each pound of raisins) and 4p (p being each pound of sunflower seeds). From this we know the second equation must be 4p+1.5r=34
It wants expanded form and the distributive property (something like 2(5+6b), so I would think it wants something like 7(200+50+6). This way, you're multiplying 7 by each expanded part of the number, which you would do anyway when solving like normal. Please correct me if I'm wrong!
Answer:
d) x = 72°
Step-by-step explanation:
Corresponding Angles: The pair of angles formed on the same side of traversal which crosses two parallel lines is called a pair of corresponding angles.
These angles are EQUAL to each other.
Now, here in the given figure:
The two below lines are parallel to each other.
Also, the line crossing it on the right side forms a traversal.
So angle x and angle with 72 degrees form a pair of Corresponding Angles.
⇒ x = 72°
Hence the measure of angle x = 72°
