To factor 8x² + bx + 3, a student correctly rewrites the trinomial as 8x^2 +px+qx+3. What is the value of pq?

(The product of the first coefficient and the constant).

3x + 4y = 5 x- 3y = -7 solve by substitution

Awater truck is filling a swimming pool. the equation that represents this relationship is y=19.75x where y is the number of gallons of water in the pool and x is the number of minutes the truck has been filling the pool.
