Answer:
X and Y = 4
Well, it's a right triangle. The red box means 90 degree angle. So I would say that all the sides are equal.
A) dilation, because size is changed by a factor/ratio
It’s 2 times the variable
768 ÷ 32 = 24
32 × 24 = 768
I hope this helps you!!
please make my answer brainliest to help me out!!!!
Thanks!!
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
