Step-by-step explanation:

Since the right parts of the equation are equal, therefore the left parts of the equation are also equal:

Divide both parts of the equation by 2:

So we have 299790000, we want to have only one digit in front of the decimal, 2.9979x10^9
hope this helps :)
X=4. If k is the midpoint then JK is equal to KL. Since JK is 7 then KL is also 7 meaning JK is 14. JK is represented by the expression 4x-2 so you just set that expression equal to 14 and solve for x. Hope this helped!
U would put it into a calculator
The solution is -5/4= -1 1/4
