Answer:
8 cm
Step-by-step explanation:
Megan's scale of drawing : car is 3cm : 2m
or
3 cm drawing ---> 2m actual length
1 cm drawing ---> (2/3) m actual length
Given Megan's drawing is 6 cm, hence,
6 cm drawing ----> (2/3) x 6 m = 4 m
Hence the actual car is 4 m long
Ivan's scale of drawing:car is 2cm : 1m
or
1 m actual length ---> 2 cm drawing
we know from above that the actual car is 4m long, so
4m actual length ---> 2cm x 4 = 8 cm drawing length.

Answer:
A. and B. are true.
Step-by-step explanation:
For a, -4 + 3(-5) = -19, and 18 is obviously greater.
For b, -7 - 2(-5) = 3, and 3 is greater than 1.
X^2+14x
To make it as perfect square binomial first divide the numerical coefficient of 14 by 2 which is 7. Then square the result[7] which is 49 and add it to the equation
x^2+14x+49
After that think of a number that has a square root of 49 then when u multiply the second term in the perfect square by the first and 2 it results to 14. So the answer is
[x+7]^2
