Answer:
550-554
Step-by-step explanation:
550 is rounded to 550, and also rounded to 600. Same with all the other numbers. :)
Part 1:
a = 2
b = 4
c = -3
Part 2: the parabola will open up
Part 3: axis of symmetry x = -1
since each block is 3/8 of a mile, then how many miles in 4½? well, it'd just be their product, but let's firstly convert the mixed fraction to improper.

All triangles in this shape have same area as they have same base length and height length.
- area of triangle: 1/2 * base * height
Here the base is 4.2 cm and height is 2.5 cm for all the given triangles.
As a result, we can say that the area of
A,
B,
C are equal.
The first factor must be at least 1 and less than 10.
The second factor must be a power of 10.
Move the decimal point to the left until the number is between 1 and 10. Count how many places you move the decimal point.23.6 → 2.36
You moved the decimal point 1 place to the left. The power of 10 is 10 to the power of 1
23.6 = 2.36 × 10 to the power of 1
