Answer:
- x³ - 15x² - 61x - 36
Step-by-step explanation:
Given
(x² - 5x - 4)(x² + 4x + 9)
Each term in the second factor is multiplied by each term in the first factor, that is
x²(x² + 4x + 9) - 5x(x² + 4x + 9) - 4(x² + 4x + 9) ← distribute parenthesis
= + 4x³ + 9x² - 5x³ - 20x² - 45x - 4x² - 16x - 36 ← collect like terms
= - x³ - 15x² - 61x - 36
Answer:
Step-by-step explanation:
How do u find the scale factor of a dilation?
To find the scale factor for a dilation, we find the center point of dilation and measure the distance from this center point to a point on the preimage and also the distance from the center point to a point on the image. The ratio of these distances gives us the scale factor, as Math Bits Notebook accurately states
Hi!
This equation is written in ' y = mx + b ' form, where m is the slope, and b is the y-intercept.
Therefore, looking at this equation, we can see that 16 is the y-intercept.
Hope this helps! Let me know if you need any other help :D
Answer:
12:28 = 3:7
Step-by-step explanation:
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 12 and 28 is 4
Divide both terms by the GCF, 4:
12 ÷ 4 = 3
28 ÷ 4 = 7
The ratio 12 : 28 can be reduced to lowest terms by dividing both terms by the GCF = 4 :
12 : 28 = 3 : 7
Therefore:
12 : 28 = 3 : 7
