Answer:
70.71cm2
Step-by-step explanation:
2*5*7.071 = 70.71cm2
set it up like a y= equation.
which would be y=-x^2+7
to find the vertex, you substitute the 0s.
so 0=-(0)^2+7
-0^2=0
0+7=7
0=7
(0,7)

she bought 10 pencils and 5 erasers
Let x represent the number of pencils and y represent the number of erasers.
Gabby wants to spend exactly $2.00 on pencils and erasers, hence:
0.15x - 0.1y = 2 (1)
Therefore x = 10 and y = 5
Therefore she bought 10 pencils and 5 erasers.
