Answer:
Step-by-step explanation:
Graph the points and draw an aproximate line of fit that includes two of the points. Then using point-slope form find the linear equation of that line.
10-(-4)=m(-5-4) is 14=m(-9) solve for m and find the slope is aproxx -14/9 or -1.555. Then do some fancy math to find your y intercept and you come out with an aproxx line of fit of y=(-14/9)x+(20/9). Or you could plug these points into excel and have it spit out a trendline of y=(-1.26)x+(0.467)

Answer:
Side N: 20
Equation: 5 × 4 = 20
Step-by-step explanation:
Look at the other sides, and try to find a "pattern". Just by looking at the bottoms of the triangles, I saw 4 on BC and 16 on FG. I know that 4 times 4 equals 16, so that could be and option.
Now look at the left side. AB has a length of 3, and EF has a length of 12. I know that 3 times 4 is 12. Both times, there was an increase of 4 between the sides of the triangles.
Now, let's apply this to the last side. 5 times 4 is 20. So, the last side would be 20 on triangle EFG, and the equation would be 5 × 4 = 20.
Answer:
(3x - 2) (x+5)
Step-by-step explanation:
3x^2 + 13 - 10
15× - 2 = -30
15+-2 = 13.....substitute 15x - 2x in place of 13x
3x^2+15x-2x-10
Factorise the first two values, thrn the second two
3x (x+5) - 2 (x+5)
Gathering the like terms together you eill be left with the following
(3x - 2) (x+5)
