9 is 60000
and 11 is 600km is larger
Answer:
28.8
Step-by-step explanation:
23+2x+3x+13=180 simplify the left side
5x+36=180 subtract 36 from both sides
5x=144 divide both sides by 5 to isolate the variable
x=28.8

The concrete operational stage is the third phase in Piaget's cognitive development theory. This period spans the period between childhood, it begins around 7 years of age and continues until about 11 years of age and is characterized by the development of logical thinking.
Answer:
2(x+1)²-3
Step-by-step explanation:
Using the vertex formula we can write the follwoing equation
y=a(x+1)²-3
We need to solve for a
we know that when x= 2 y = 15
So we can write
15=a(2+1)²-3
15=9a-3
18=9a
a=2
Which means our final equation is
2(x+1)²-3
in standard form (just in case)
2x²+4x-1
Answer:
y=1/2x²
Step-by-step explanation:
y=2x-²
y=1/2x²
