Can someone help me solve this proof for properties of equality geometry ty

4. find the geometric mean of 4 and 12. 24 8

The table below shows the height of a ball  x  seconds after being kicked.  what values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x)  =  x2  +  x  +  0based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds?   feet

The reflexive property of congruence lets you say that ∠pqr ≅
