Step-by-step explanation:
you need to find out how many poeple u have first
The greater is 150 ounces
51% less.
The length is decreased by 50%, which is the same as being multiplied by 0.5, then it's increased by 40% which is another multiplication by 1.4. So the overall change is 0.5 * 1.4 = 0.7, or the newest rectangle is 70% of the size of the original rectangle. And since the area increases by the square, the newest rectangle has 0.7 * 0.7 = 0.49 of the area as the original rectangle. So it has 51% less area than the original rectangle.
25. 3y+15
26. 15k+20
27. 21n+7p
28. 60w+20x
Also, you got number 19, number 21, and number 24 wrong.
D+D+D+D+D = 5D, not D⁵
S+S+S = 3S, not S³
N+N+N+N = 4N, not N⁴
Remember, repeated addition, (n+n+n) is 3n. Repeated multiplication, (n•n•n) is n³.
Hope this helps.
