Ummmm i believe your answer is A. just divide next time :)
4x²-12x+9=5
4x²-12x+4=0
x= 12±√(144-4*4*4) / 2*4
x= 12 ± √(144-64) / 8
x=12±√80. /. 8
x= 12+4√5. /8
x=3±√5 / 2. C and E
Answer:
12 times
Step-by-step explanation:
12x12 is 144 so there for 12 goes into 144 12 times
To solve for x, we will begin by using the distributive property
6x - 2(x + 4) = 12
6x - 2x - 8 = 12
(always remember to sort your negatives!)
Add like terms
4x - 8 = 12
Add 8 to both sides
4x = 20
Divide both sides by 4
x = 5
Answer:
7 gallons
Step-by-step explanation:
Step 1:
80 : 5 = 112 : x
Step 2:
80x = 560
Answer:
x = 7
Hope This Helps :)
