Answer:
2400
Step-by-step explanation:
Step 1: Turn 0.5 into a whole number.
Step 2: Divide 12 by 5.
Step 3: Multiply 2.4 by 1000
Therefore, the answer is 2400.

Answer:
c.
Step-by-step explanation:
32(0.62)= 19.84 round up so the answer is 20.
Distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2
(-10,5)....x1 = -10 and y1 = 5
(-8,-3)....x2 = -8 and y2 = -3
now sub
d = sqrt ((-8 - (-10)^2 + (-3 - 5)^2)
d = sqrt ((-8 + 10)^2 + (-8^2)
d = sqrt (2^2) + (-8^2)
d = sqrt (4 + 64)
d = sqrt 68
d = 8.25 <====
Let s represent the length of any one side of the original square. The longer side of the resulting rectangle is s + 9 and the shorter side s - 2.
The area of this rectangle is (s+9)(s-2) = 60 in^2.
This is a quadratic equation and can be solved using various methods. Let's rewrite this equation in standard form: s^2 + 7s - 18 = 60, or:
s^2 + 7s - 78 = 0. This factors as follows: (s+13)(s-6)=0, so that s = -13 and s= 6. Discard s = -13, since the side length cannot be negative. Then s = 6, and the area of the original square was 36 in^2.
