We are asked in the problem to get the linear equations that results to 2x2 =x2 + 4x +8. In this case, the two equations on each sides can be equal to y in which the two equations are then identical. The systems of equations that has the right answer is C.
Answer with Step-by-step explanation:
The number of marbles are as under
3 red , 3 green , 1 Lavender total = 7
Now to select five marbles from a total of 7 marbles such that at least 2 marbles are included are the sum of the following cases:
1) We select 2 exactly 2 red marbles from 3 reds and the remaining 3 marbles are selected from 4 of other colours
Thus 
2)We select all the 3 red marbles and the remaining 2 are selected from the remaining 4 marbles
Thus the total number of ways are 
Answer:
49
Step-by-step explanation:
the number a negative so you basically subtracting
Answer:
3/20
Step-by-step explanation:
15 and 100 both have a common factor of <em>5</em>. To simply an expression, you have to get both the numerator (top number) and the denominator (bottom number) to be as low as possible (to make it so that both can't be divided anymore or don't have shared factors). We divide both sides by 5 (which still retains as an integer and has the same value) and so 15/3=5 and 100/5=20.
Have a nice day! :)
Just count the zeros at the left. In your case <span>6
</span> so your number equals <span><span>0.428⋅<span>10<span>−6</span></span></span>
</span> and in scientific <span>4.28⋅<span>10<span>−<span>7</span></span></span></span>
