(3a-7)^2
1. 9a^2-21a-21a+49
2. 3a(3a-7)-7(3a-7)
3. (3a-7)(3a-7)
4. Combine like terms
Simplify:
37 - (-3)^2 + 30/(-3)x^2
= 37 + - 9 + - 10x^2
Combine like terms:
= 37 + - 9 + - 10x^2
= ( - 10x^2) + (37 + - 90
= - 10X^2 + 28
Answer: - 10x^2 + 28
To Factor:
37 - (- 3)^2 + 30/- 3x^2
- 10x^2 + 28
- 2(5x^2 - 14)
Answer: - 2(5x^2 - 14)
I simplify, and factor, because, you didn't really specify what you wanted help on with this equation. - Thanks -
Hope that helps!!!!
Answer:
18
Step-by-step explanation:
24=8×3
If F=24 when A=8 then F is directly proportional to A•3
Using proportions, it is found that the coordinates of point P are given as follows: (2,10).
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The segment is partitioned by point P according to the ratio of 3:4, hence:
![P - A = \frac{3}{7}(B - A)](https://tex.z-dn.net/?f=P%20-%20A%20%3D%20%5Cfrac%7B3%7D%7B7%7D%28B%20-%20A%29)
This proportion is applied for both coordinates, hence, for the x-coordinate:
![x - 2 = \frac{3}{7}(2 - 2)](https://tex.z-dn.net/?f=x%20-%202%20%3D%20%5Cfrac%7B3%7D%7B7%7D%282%20-%202%29)
x - 2 = 0
x = 2.
For the y-coordinate:
![y - 4 = \frac{3}{7}(18 - 4)](https://tex.z-dn.net/?f=y%20-%204%20%3D%20%5Cfrac%7B3%7D%7B7%7D%2818%20-%204%29)
y - 4 = 6
y = 10.
Hence the coordinates are (2,10).
