The answer is B. because (4-10) equals -6 and (4-4) equals 0. -6 times 0 is 0.
2y+4=3(y-1)
2y+4=3y-3
4+3=3y-2y
Y=7
X=2
Starting with the least score it would be ; 9.25 , 9.325 , 9.5 , 9.675
Use algo como cymath. It’s a calculator and it works very well
Using the Pythagoras theorem
8^2 = 5^2 + x^2 where x = 1/2 length of the base
x^2 = 64-25 = 39
x = = sqrt39 = 6.24
so base length = 2*6.24 = 12.5 cm to nearest tenth
