Answer:
x = ± 2i
Step-by-step explanation:
The equation has no real roots, gut has complex roots
Given
x² = - 4 ( take the square root of both sides )
x = ± 
= ± 
[ Note that
= i ]
= ±
×
= ± 2i
Take 0.5x4x3=6 So the answer is 6.
Y =Mx + C
where M = gradient / slope
C = y intercept
comparing with y = 2x - 3
M = 2
C = -3
40.75 - 7.05= 33.7
33.7 / 2 = 16.85
16.85 ft. should be on each side of the 7.05 ft. bench
7 days because 12 per day 12×6=72 but you need 3 more acres so it would be another day for it to be 7
