Ahmad made 4 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 4 necklaces

yanalaym [24]

$6.40
All beads and pendants = $19.20, and the beads equal $12.80, so 12.80 + ? = 19.20. So you would use the equation. 19.20 - 12.80, which equals 6.40.

Determine the number that will complete the square to solve the equation after the constant term has been written on the right s

klemol [59]

Answer:

Step-by-step explanation:

Hello, "the constant term has been written on the right side", it means that we add 18 to both sides to get.

$x^2+3x-18=0\\\\x^2+3x=18\\\\\text{We can see the beginning of } (x+\dfrac{3}{2})^2 \\\\x^2+3x=(x+\dfrac{3}{2})^2-\dfrac{3^3}{2^2}=18\\\\(x+\dfrac{3}{2})^2=18+\dfrac{9}{4}=\dfrac{18*4+9}{4}=\dfrac{81}{4}$

Hope this helps.

Thank you.
