1. What is the value of 5x² – 3x + 5 when
x=2?
2 answers:
Answer:
<em>624 is the answer</em>
Step-by-step explanation:
5x²-3x+5 x=2
plug in x=2: 25²-6+5=?
do the 25²: (25*25=625)
plug in 625 into the equation: 625-6+5
subtract 6 from 625: 625- 6= 619
plug 619 into your equation: 619+5=?
add 5 to 619: 619+5= 624
Answer:
