1<span>, 4, 7, 10 is a sequence starting with </span>1<span>. You get the next </span>term<span> by adding 3 to the previous </span>term. You are often asked to find a formula for the nth term<span>. As the common difference is 3, try </span>3n<span>. When n = </span>1<span>, </span>3n<span> = 3, and we subtract 2 to make the first </span>term<span> correct.</span>

Let the constant stretch factor be x
then
3x + 4x + 2x = 72 Add the left side.
9x = 72 Divide by 9
x = 72/9
x = 8
Therefore the sides are
8*3 = 24
8*4 = 32
8*2 = 16
Total = 72 which checks.
Hi
6% increase is multiply by 1,06
done 40 times
so : 250* 1,06^40 = 2571 ,
Answer:
x = 7
T(7, 3)
Step-by-step explanation:
The slope of the line is the same everywhere, so the ratio of y-differences to x-differences is constant.
Differences between R and S:
S -R = (-1, -1) -(-5, -3) = (-1+5, -1+3) = (4, 2)
T -R = (x, 3) -(-5, -3) = (x+5, 3+3) = (x+5, 6)
Then the ratios of y-differences to x-differences are ...
2/4 = 6/(x+5)
2(x+5) = 4(6) . . . . cross multiply
2x +10 = 24 . . . . . simplify
2x = 14 . . . . . . . . subtract 10
x = 7 . . . . . . . . . . divide by 2
Point T is (7, 3). . . . . . . . (x=7)
