Answer:
a. 10√2
Step-by-step explanation:
hey, just use Pythagoras theorem
h²=p²+b²=10²+10²=100+100=200
h²=200, h= √200 =√(100×2)=√100×√2=10√2
Step-by-step explanation:
x² - 14x - 51 = 0
(x² - 17x) + (3x - 51) = 0
x(x - 17) + 3(x - 17) = 0
(x + 3) (x - 17) = 0
x + 3 = 0 eq1
x = 0 - 3
x = -3
x - 17 = 0 eq1
x = 0 + 17
x = 17
