Answer:
1/16
Step-by-step explanation:
Here: 64x^2+12x = 1
Then, 64x^2 +12x -1=0
The delta = 12^2 - 4*64*(-1)= 400 = 20^2
These two solutions are:
(-12+20)/(2*64)= 8/(2*8*8)= 1/16
(-12-20)/(2*64) but this is negatif.
1/16 is the positif solution.
Hope that useful for you.
Answer:
x = -1.8
Step-by-step explanation:
10(-1.8) - 2 = -18 - 2 = -20
so X = -1.8
Answer:
Total volume = 355 cm³
Step-by-step explanation:
Volume of the irregular prism = volume of part A + volume of part B
Volume of part A which is also a rectangular prism = Length × width × height
= (11 - 5) × 5 × 6
= 6 × 5 × 6
= 180 cm³
Volume of rectangular prism B = 5 × 5 × (6 + 5)
= 5 × 5 × 11
= 275 cm³
Total volume = 180 + 175
= 355 cm³
