4 ( 3x + 2x + 6 ) = 4 ( 5x + 6 ) = 4 ( 5x ) + 4 ( 6 ) = 20x + 24
The answer is D, hope this helped.
Answer:
A. It will be multiplied by 4.
Step-by-step explanation:
When all the dimensions of a 2-dimensional figure are multiplied by a number x then the area is multiplied by x^2. Since all numbers are multiplied by 2 then the area will be multiplied by 2^2 or 4.
To prove this:
12*14=168
Now double the dimensions
24*28=672
Notice that 168*4=672

I can see the question but if you add a picture maybe i’ll understand it a little more
Y = -t ^ 2 + 300t - 16
We find the first derivative and calculate its roots.
We make the second derivative, and calculate the sign taken in it by the roots of the first derivative, and if:
f '' (a) <0 is a relative maximum
f '' (a)> 0 is a relative minimum
y '= - 2t + 300 = 0
-2t + 300 = 0
t = 300/2 = 150
y'' = - 2
y'' (150) = - 2 (is a relative maximum)
the highest point of the trajectory is reached for t = 150s.
The height for that time is
y = - (150) ^ 2 + 300 (150) - 16 = 67484
answer
67484
t = 150s.
