Divide the value of "b" by 2 and then square it.
(b / 2)²
= (120 / 2)²
= (60)²
= 3600
Therefore the value of z is 3600. That's at least what I believe lol
Answer: 604/25=24 4/25

A) 12 and 33 can be divided by 3 so 12:33 = 4:11
B= 20 and 5 can be divided by 5 so 20mm:5mm = 4mm:1mm
Hello :
<span>y²-2y=-9/2
(y²-2y +1) -1 = -9/2
(y-1)² = -7/2
in : R no solutions
in : C two solutions
y-1 =-(</span><span>√</span>7/2)i or y-1 = (√<span>7/2)i
y = 1 -(</span>√7/2)i or y = 1+(√<span>7/2) i because : -7/2 =(7/2)i²... i² = -1
</span>
