The simplified form of the expression 3x² * 2x² is 6x⁴.
To simplify the expression 3x² * 2x², we need to multiply the coefficients and add the exponents of the variables.
Step 1: Multiply the coefficients (numbers in front of the variables):
3 * 2 = 6
Step 2: Add the exponents of the variables (x² * x² = x²⁺² = x⁴):
x² * x² = x²⁺² = x⁴
Step 3: Put the results together:
6x⁴
Therefore, the simplified form of the expression 3x² * 2x² is 6x⁴.
In summary, when multiplying two terms with the same variable (x) raised to a power (exponent), we multiply their coefficients (3 and 2, which results in 6) and add their exponents (2 and 2, which results in 4). The final answer is 6x⁴, where 6 is the coefficient and x⁴ represents the variable raised to the power of 4. This calculation follows the rules of multiplying terms with variables and exponents.

Answer:
After 7.8 hours (7 hours 48 min.) will the bus and car be 800 miles apart
70(h-2) expression represents the number of miles the car travels.
Step-by-step explanation:
If h represents the number of hours the bus travels.
In the question it is said that the bus leaves 2 hours before the car does
Therefore car travels (Time) = ( h-2 )
car's speed = 70 mph,
Distance = speed × time = 70(h-2)
70(h - 2) expression represents the number of miles the car travels.
If we want to find the number of hours will the bus and car be 800 miles apart we can solve it as :
50h + 70(h-2) = 800
50h + 70h - 140 = 800
120h = 800 + 140
120h = 940
h = 940 ÷ 120 = 7.833... = 7.8 hours (7 hours and 48 min.)
Ans. After the bus left the city, after 7.8 hours the car and the bus will be 800 miles apart.
The algebraic expression for the quotient of 17 and K is 17/K.
The algebraic expression for the quotient of 17 and K is 17/K. In algebra, division is represented by the forward slash symbol (/). So, when you divide 17 by a variable K, the quotient is expressed as 17/K.
