Answer: x = 4
Step-by-step explanation: 4x^2−32x+64=0
4(x−4)(x−4)=0
x−4=0 x−4=0
x=4
The answer is 5
a^2+b^2=c^2
9+16=25
sq root of 25 is 5
A^2 + b^2 = c^2
5^2 + b^2 = 20^2
25 + b^2 = 400
b^2 = 375
b = 19.4 feet
Answer:
sometimes
Step-by-step explanation:
Similar figures can also be a different size, as long as they're the same shape. So both rigid transformations and dilations can create similar figures.
1/2bh
1/2b4 = 18
