Q1. Solve the equation 2r2 - 11r - 21 = 0.
Give the answer

The values of r = -3/2 ,7

Step-by-step explanation:

2r2 - 11r - 21 = 0.

The is a quadratic equation in the form

2r²-11r -21= 0

Let's determine the value of r using factorization method

2r² -14r +3r -21= 0.

2r(r-7)+3(r-7)= 0

(2r+3)(r-7)= 0

2r+3= 0

2r= -3

r= -3/2

And

r-7= 0

r= 7

The values of r = -3/2 ,7

step-by-step explanation:

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier
