9 x 20 = 180
4(2x 2) = 16
180+16 = 196
answer
area of figure = 196
The answer to your question is <span>8(n-3)=64</span>
-18 is 18 below the zero on a number line and 104 is 104 above the 0 on the number line. If you go from -18 toward the zero and continue to 104 it will give you 122 degrees. another way is to add 104 and 18. Hope that helps
To find equivalent ratios just factor the same number to both numerator and denominator. I will make the ratios simple by multiplying 2/2 and 3/3 to the originals. To check, set as fraction and cross multiply and you should have the same number. I will show you how to check by doing it to the first ratio.
8:5 16:10 24:15
Check:
8/5 = 16/10
(8)(10)=(5)(16)
80=80
8/5=24/15
(8)(15)=(5)(24)
120=120
4:19 8:38 12:57
6:23 12:46 18:69
1.
21=3*7
28=2*2*7
gcf: 7
21w+28=7(3w)+7(4)=7(3w+4)
2.
1/3p-2/3=1/3p+(-2/3)=1/3(p)+1/3(-2)=1/3(p-2)
3.
12/6=2
-42/6=-7
12y-42=12y+(-42)=6(2y)+6(-7)=6(2y-7)
