Answer:0.35
Step-by-step explanation:
It is 7, because you always have to round up if the next decimal is greater than or equal to 5 (depending on where you live).
We know that standard form = the number that is not expanded.
This equation is expanded so standard form =
2*100=200
9*10=90
6*1=6
3*1/10= 0.3
8*1/100=0.08
200+90=290
290+6=296
296+0.3=296.3
296.3+0.08=296.38
Your answer is 296.38

A = l × w. Substitute 72 into A and fill in the rest of the equation.
w = l - 1. Plug l - 1 into w
72 = l × (l - 1). Multiply l by (l - 1)
72 = l^2 - l. Subtract 72 from each side.
0 = l^2 - l - 72. Factor.
0 = (l + 8) (l - 9). Set each term equal to zero.
(l + 8) = 0. Subtract 8 from each side.
l = -8. Length cant be a negative number so let's try the other term.
(l - 9) = 0. Add 9 to each side.
l = 9. The length is 9.
Earlier we stated that the width is one less than the length, therefore, the width is 9 - 1 = 8.
The width is 8 units.
