Answer:
a. 4(d+3e)
b. 6(3x+5y)
c. 7(3a+4y)
d. 8(3f+7g)
Step-by-step explanation:
In each case we find the greatest common factor of the numbers. That is the greatest number that goes into both the numbers. Then we factor it out in front and inside parentheses we divide each original term by the greatest common factor:
a. 4d+12e, GCF: 4
![\displaystyle4\left(\frac{4d}{4}+\frac{12e}{4}\right)=4(d+3e)](https://tex.z-dn.net/?f=%5Cdisplaystyle4%5Cleft%28%5Cfrac%7B4d%7D%7B4%7D%2B%5Cfrac%7B12e%7D%7B4%7D%5Cright%29%3D4%28d%2B3e%29)
b. 18x+30y, GCF: 6
![\displaystyle6\left(\frac{18x}{6}+\frac{30y}{6}\right)=6(3x+5y)](https://tex.z-dn.net/?f=%5Cdisplaystyle6%5Cleft%28%5Cfrac%7B18x%7D%7B6%7D%2B%5Cfrac%7B30y%7D%7B6%7D%5Cright%29%3D6%283x%2B5y%29)
c. 21a+28y, GCF: 7
![\displaystyle7\left(\frac{21a}{7}+\frac{28y}{7}\right)=7(3a+4y)](https://tex.z-dn.net/?f=%5Cdisplaystyle7%5Cleft%28%5Cfrac%7B21a%7D%7B7%7D%2B%5Cfrac%7B28y%7D%7B7%7D%5Cright%29%3D7%283a%2B4y%29)
d. 24f+56g, GCF: 8
![\displaystyle8\left(\frac{24f}{8}+\frac{56g}{8}\right)=8(3f+7g)](https://tex.z-dn.net/?f=%5Cdisplaystyle8%5Cleft%28%5Cfrac%7B24f%7D%7B8%7D%2B%5Cfrac%7B56g%7D%7B8%7D%5Cright%29%3D8%283f%2B7g%29)
Answer:
-1050
Step-by-step explanation:
-650+(-400)=-1050
We use negatives to show it is below sea level

Answer:
d = 7
Step-by-step explanation:
Distance Formula: ![d = \sqrt{(x2 - x1)^2+(y2-y1)^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28x2%20-%20x1%29%5E2%2B%28y2-y1%29%5E2%7D)
Plug in our 2 coordinates:
![d = \sqrt{(2-2)^2+(1+6)^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%282-2%29%5E2%2B%281%2B6%29%5E2%7D)
And you should get 7 as your final answer.
