1) 40-25= 15
2) 15/3=5
3) each gift costs $5
Then to check:
1) 5x3=15
2) 25+15=40
Therefore p=5
2,4,6,8,10,12,14,16,18,20,
Answer:
D is the Answeer
Step-by-step explanation:
2x² + 6x - 4 = 0
2(x²) + 2(3x) - 2(2) = 0
<u>2(x² + 3x - 2)</u> = <u>0</u>
2 2
x² + 3x - 2 = 0
x = <u>-(3) +/- √((3)² - 4(1)(-2))</u>
2(1)
x = <u>-3 +/- √(9 + 8)</u>
2
x = <u>-3 +/- √(17)
</u> 2<u>
</u> x = -1.5 <u>+</u> 0.5√(17)
x = -1.5 + 0.5√(17) U x = -1.5 - 0.5√(17)
