The quadratic 3xsquared - 12x-11 can be written in the form 3(x+a) squared + b find the values of a and b

so, converting firstly the mixed fractions to improper fractions and then "adding".

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

your correct answer is c. he organized a political resistance group based on islam.

im sorry for the poor quality answer.

this would be 35. 35 + 5 = 40. you take the known constant and subtract by the answer of the equation and you get y.
