Answer:
4(2x+3)
Step-by-step explanation:
8x+12
4(2x+3)
----------------
Note that 8x+12=4(2x+3),
because we factored out 4.
Sal's answer is wrong because even though 2(4x+6)=8x+12,
but the answer 4(2x+3) is more reasonable,
because our goal is to find the largest number when factoring an expression.
2,010−2,000=10 years
P=100,236,820×(1+0.143)^(10)
P=381,495,644.68
Answer:
In a nutshell, you have to graph the parabola. Where the parabola intersects the x-axis is the solutions to the quadratic equation.
A) c = r +5B) 2*c + 4 * r = 130
Substituting A) into B)B) 2 * (r + 5) + 4 * r = 130B) 2 * r + 10 + 4 * r = 130B) 6r = 12020 rabbits and therefore 25 chickens
Double-Check
2 * 25 + 4 * 20 = 130 total legs
