Answer:
-1
Step-by-step explanation:
The required relation is ...
7n = n^2 -8
0 = n^2 -7n -8 . . . . put in standard form
0 = (n -8)(n +1) . . . . factor
Solutions are n=8 and n=-1.
The negative solution is -1.
Answer:
W=5.3, l= 15.6
Step-by-step explanation:
Perimeter of a rectangle p=2(l+w)
P= 42
W= x
L= 5+2x therefore 42=2(5+2x+x)
42=10+6x , 32=6x
Make x subject of formula
X=32/6 x=5.3 there for w=5.3
Where L= 5+2x ; L=5+2(5.3)
L therefore = 15.6
One option for the final answer is 30 and 22...
I think I would use the second answer that you provided
Answer:
7/8
Step-by-step explanation:
The fraction closest to 1 is 7/8 because it is only 1/8 piece away from one.
Area of the figure = 27 square units
Solution:
Number of full squares shaded = 24
Number of half squares shaded = 0
Number of more than half square shaded = 3
Number of less than half square shaded = 4
Area of the figure = Number of full square + Number of more than half square
+ Half of number of half squares
= 24 + 3
= 27 square units.
Area of the figure = 27 square units
