Answer:
8x^2+19x
Step-by-step explanation:
Simplify the expression by combining like terms. Terms which look a like and sound a like should be added together.
3x^2+7x+3+5x^2+12x
x^2 terms: 3x^2+5x^2=8x^2
x terms: 7x+12x=19x
constants: 3
Together is is 8x^2+19x+3.
Answer:
3/50 7/50 40/50
Step-by-step explanation:
Ok. I'm not exactly a math wiz but I think you may be overthinking this. Experimental probability should be the probability from the experiment right. It's in the name. In chemistry if it's a well established value it's called a theoretical value or probability. So the answer should just be the probability from the said experiment. No other funky math terms are given here which clues me to the idea that it might just be this simple.
X^2 - 14x + 42 = 0
x^2 - 14x = -42
x^2 - 14x + 49 = 49 - 42
(x - 7)^2 = 7
x - 7 = (+-) sqrt 7
x = 7 (+-) sqrt 7
solutions are : x = 7 + sqrt 7 and x = 7 - sqrt 7
510 = (1700)(6)(t)
510 = 10200t
0.05 = T
Answer:
the third option would be the best
Step-by-step explanation:
2/7 + 3/8 = 37/56 = .660
1/10 + 3/8 = 19/40 = .475
correct answer------------ 1/6 + 1/8 = 7/24 = .291
2/9 + 1/8 = 25/72 = .347
