Answer:
Number of marbles Andrea has can be expressed as =
marbles
Step-by-step explanation:
Given:
Number of marbles Jennifer has = 
marbles
Andrea has 4 times the number of marbles that Jennifer has.
∴ Number of marbles Andrea has can be expressed as = 
marbles
To solve, simply layout an equation.
(2x+3)(x+4)=1
Step 1: Simplify both sides of the equation.
2x2+11x+12=1
Step 2: Subtract 1 from both sides.
2x2+11x+12−1=1−1
2x2+11x+11=0
Step 3: Use quadratic formula with a=2, b=11, c=11.
x=-b±√b^2-4ac/2a
So, the answer for this problem is:
x=-11/4+1/4√33 or -11/4+-1/4√33
