Hi,
AxB = 0 means A=0. or B=0
so 2 solutions :
4x-3= 0
4x=3
x = 3/4
and x+2 = 0.
x= -2
solutions are : -2 +and 3/4
Answer:
i feel like correct answrr would be C. Hope this helps!!!
Answer:
The answer is: 83 + 12√35
(a + b)² = a² + 2ab + b²
In (2√5 + 3√7)², a = 2√5, b = 3√7
Just substitute a and b:
(a + b)² = a² + 2ab + b² = (2√5)² + 2 * 2√5 * 3√7 + (3√7)² =
= 2²√5² + 2 * 2 * 3 * √5 * √7 + 3²√7² =
= 4 * 5 + 12 * √(5*7) + 9 * 7 =
= 20 + 12 *√35 + 63 =
= 83 + 12√35
Step-by-step explanation:
Answer:
Gallons in each tank= 5.4 G
Gallons in 2 fish tanks= 10.8 G
Step-by-step explanation:
To find the gallons of water in each tank, divide 27 gallons by 5 fish tanks.
27/5= 5.4
To find the number of gallons to fill 2 fish tanks, multiply 5.4 (gallons in 1 tank) by 2 (2 tanks).
5.4*2= 10.8
