Answer: x=12

This solution is not extraneous

Step-by-step explanation:

\frac{-4\sqrt{x-3}}{-4}=\frac{-12}{-4}  Divide both sides by -4

\sqrt{x-3}=3 Simplify

\left(\sqrt{x-3}\right)^2=3^2 Square both sides

3^2=9

x-3=9

add 3 on both sides

9+3=12

x=12

Al, Pablo, and Marsha shared the driving on a 1,500-mile trip. Which of the three drove the greatest distance on the trip?(1) Al
Svetach [21]

Answer:

Pablo drove the greatest distance of 527 miles.

Missing Content:

Since information on Pablo is not given, it is impossible to solve this problem. Let us assume some scenario for Pablo. Say:

(3)Pablo averaged 52.7 miles per hour and drove for 10 hours.

Step-by-step explanation:

Using this information, we can find out the data on Al,

Al drove 1 hour longer than Pablo so,

Time Al drove= 10+1 =11 hours

Average rate of Al=Pablo's average rate-5= 52.7-5 = 47.7 miles per hour.

We know that,

Average Speed = \frac{Distance}{Time}

Distance =Average Speed x Time

Distance travelled by Al = 47.7 x 11 =524.7 miles

Distance Travelled by Marsha = 50 x 9=450 miles

Distance Travelled by Pablo= 52.7 x 10= 527 miles

<u>As we can see that Pablo drove the greatest distance which is 527 miles.</u>

Find product of :(2x-y)(2x+3y).​
Ierofanga [76]

Answer: 4x² + 4xy - 3y²

Concept:

When encountering questions that ask for simplifying algebraic expressions, using the FOIL method would be easier:

  • <u>First</u>, which means multiplying the first terms together;
  • <u>Outer</u>, which means that we multiply the outermost terms when the binomials are placed side by side;
  • <u>Inner</u>, which means multiply the innermost terms together;
  • <u>Last</u>, which means that we multiply the last term in each binomial together.

Solve:

<u>Given</u>

(2x - y) (2x + 3y)

<u>Expand parentheses and apply the FOIL method</u>

=4x² + 6xy - 2xy - 3y²

<u>Combine like terms</u>

=4x² + (6xy - 2xy) - 3y²

=\boxed{4x^2+4xy-3y^2}

Hope this helps!! :)
