4. solve the equation 30a2 – 7 = 29a.

Value of a = 7/6 and a = -1/5

Step-by-step explanation:

We need to solve the equation

30a^2 -7 = 29a

Adding -29a on both sides

30a^2-29a-7=0

Solving the quadratic equation using quadratic formula.

here a= 30, b =-29 and c=-7

Putting values, and finding the value of a

So, value of a = 7/6 and a = -1/5

grab rope, tie a loop-de-loop, put it around ur neck, now jump while its tied to a high place. now your shoes are cool.

step-by-step explanation:

      2

  2 is to go somewhat to the top right of a because it is squared
