Sub in 4 for x and multiply so it would be 112 + 30 + 16 which is 158
Answer:
1. Communitave property
2. communitave property
3.
1. distribute 2 to x and 10 to get ride of parenthesis
2. subtract 2x from the left to move it to the right so x is by itself
3. add 15 to both sides to cancel it out on one side, and move to the other.
4. divide by 5 on both sides so you can get the value of x
5. flip equation so it is in the x equals form
4.
1. distribute 2 to the x and positive 3 on the left side, also distribute -4 to both x and -1 , to get rid of our parenthesis.
2. add 4x to both sides so it cancels out on one side and moves to the other ( our xs and numbers need to be on opposite sides)
3. subtract 4 on the left side to move it to the right side because again numbers on the right and letters on the left
4. divide by 6 on both sides of the equation to solve for x

Answer:
1092.50 account value
142.50 interest
Step-by-step explanation:
to solve compound interest questions we use the formula A=P(1+rt) where P is the principal (initial investment) r is the rate or the return (7.5%) and t is the interval or time so 2 years
now putting it together we get A=950(1+ (7.5x2)) = 1092.50 $
the interest is this value A minus the initial investmetn so 1092.50 - 950 = 142.50$
