Answer:
19
Step-by-step explanation:
9+10 is 19.
Answer:
the factor of 25 is : 1, 5, 25
X + 0.12x = 31360
1.12x = 31360
x = 31360/1.12
x = 28,000 <===
I am not familiar with "brighten" but this is how you can expand and use the distributive property:
7(256)
= 7(200 + 50 + 6)
= 7(200) + 7(50) + 7(6)
= 1400 + 350 + 30
= 1780
Answer:

Step-by-step explanation:
y = x² - 10x + 27
y = ax² + bx + c
This is the general form of the equation for a parabola.
We must convert it to the vertex form
y = (x - h)² + k, where (h,k) are the coordinates of the vertex.
We can do this by completing the square.
The figure below shows that your parabola has its vertex at (5,2).
