The model shows the expression 20 + 16. Which expression is equivalent to this sum?
O4(5) + 4
4+5+4
O4(5+4)
5(4+4)

Solve -2(4y + 6) = 52. 5 -5 8 -8 and !

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions. a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

1.two more than the quotient of a number and 6 is equal to 7 use the c for the unknown number translate the sentence into an equation
