Answer:
Total charge= -25
Step-by-step explanation:
Given :
Charges of some ions
Aluminium +3
Phosphate -3
Chloride -1
Silver +1
To find total charge on 8 phosphate,7 chloride and 2 Aluminium atoms
Aluminium +3 × 2 =+6
Phosphate -3 × 8 = -24
Chloride -1 × 7 = -7
total charge=
+6-24-7 =+6 -31
= -25
One way of calculating the volume would be to convert all of these measurements to decimal:
V = (18 in)(30 in)(8 in) = 4320 cubic in
Answer: 19 cm
<u>Step-by-step explanation:</u>
99 = 
99 = 
198 = (2x + 13)(x - 4)
198 = 2x² + 5x - 52
0 = 2x² + 5x - 250
0 = 2x²- 20x + 25x - 250
0 = 2x(x - 10) + 25( x - 10)
0 = (2x + 25)(x - 10)
0 = 2x + 25 or 0 = x - 10
= x or x = 10
Since length cannot be negative, can be disregarded
Larger base: x + 9 = 10 + 9 = 19
Answer: 3x^2 + 25x + 1
Step-by-step explanation:
3C + B
=> 3(x^2 + 8x + 3) + (x - 8)
=> 3x^2 + 24x + 9 + x - 8
=> 3x^2 + 25x + 1
