Answer:
or
27 
Step-by-step explanation:
Any regular whole number (37 for example) is over one so it would look like
. Multiplying fractions involve just multiplying the numerators and denominators together, therefore it would look like
×
. Now just multiply the top and bottom numbers together and this will leave you with
. But if you'd like to make it into a mixed number (more simplified version of
) then you would get 27
.
Step-by-step explanation:
upper left angle and lower right are the same in a parallelogram (the other two angles match as well, but aren't useful)
so we can write this equation:
3x -15 = 2x +24
1x -15 = 24
x = 39
always do the same thing on both sides of an equation (here: subtract 2x, then add 15)
now you might give it a try yourself with the next problem that got two same things in it.

Area of a square = length²
A = x²
16 = x²; x = 4
dA/dx = 2x cm²/s
dx/dt = 6 cm/s
Using chain rule:
dA/dt = dA/dx * dx/dt
dA/dt = 2x * 6
dA/dt = 12x
At x = 4,
dA/dt = 12(4) = 48 cm²/s
