3 0

Answer:

(2x+3)(x-7)

Step-by-step explanation:

✯Hello✯

↪  First you are going to want to equally split the equation into separate brackets - I've done this as (2x^2+3)+(-14x-21)

↪  Further factorise this x(2x+3)

↪  From the other bracet factor -7(2x+3)

↪  they have a common term in which we can use to make new brackets  

(2x+3)(x-7)

HOPE THIS HELPS

A car was driving for 4 hours and covered 225 miles. A high-speed train is ten times as fast as this car. Find the train's speed
Lubov Fominskaja [6]

Answer:

562.5 mph

Step-by-step explanation:

First, let's find how fast the car is going in miles per hour. We do this by dividing the miles by how many hours it took:

225/4 = 56.25

The car was going 56.25 mph

A high-speed train is ten times faster than this car so you multiply 56.25 by 10

(10)(56.25) = 562.5

The train's speed is 562.5 mph

<em>Hope this helps!</em>
