Answer:
- 4x² - 8x - 3
Step-by-step explanation:
We want to calculate
1 - (2x + 2)² ← expand using FOIL
= 1 - (4x² + 8x + 4) ← distribute parenthesis by - 1
= 1 - 4x² - 8x - 4 ← collect like terms
= - 4x² - 8x - 3
3/4 - 1/3 = 9/12 - 4/12 = 5/12
(5/12) / 10 = 1 / x
5/12x = 10
x = 10* 12/5
x = 120/5 = 24 gallons...so when full, the tank holds 24 gallons
so if it is already 3/4 full, then u just need 1/4 to fill
1/4(24) = 24/4 = 6......so u would need 6 more gallons to fill the tank up to full capacity.
Zack would receive $200. You have to make 60% as a decimal= 0.60 then multiply $500*0.60= $300 then you subtract $500-$300=$200
(Hope this works!!)

Answer:
x = 2
Step-by-step explanation:
Step 1: Write equation
3x - 5 = 1
Step 2: Solve for <em>x</em>
- Add 5 to both sides: 3x = 6
- Divide both sides by 3: x = 2
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
3(2) - 5 = 1
6 - 5 = 1
1 = 1
