<span>For three numbers to represent lengths of the sides of a triangle, the sum of
each pair must be greater than the remaining side.
A)
3 + 4 = 7
3 + 5 = 8
5 + 4 = 9
B)
2 + 5 = 7
2 + 8 = 10
5 + 8 = 13
C)
2 + 12 = 14
2 + 15 = 17
15 + 12 = 27
D)
3 + 3 = 6
3 + 7 = 10
3 + 7 = 10
In all these, only A have the sum of the numbers greater than the numbers itself. So the answer is A.

Y=x^2+3x+4
y-x=7
x^2+3x+4-x=7
x^2+2x+4=7
(factor) x^2+2x-3=0
(x+3)(x-1)=0
X= -3 and X=1
(Plug x in for y)
Y= 1^2+3(1)+4
Y=8
(Check your answer on the second equation)
8-1=7
7=7 (Which is the solution)
Answer: 2.12 × 
The coefficient (in green) will be 2.12
Step-by-step explanation:
Scientific notation is written by multiplying the number by a power of 10. This number is a number between 1 and 10.
Since this is a smaller number, we will be multiplying it by a power of 10 to a negative number.
To get this value to a number between 1 and 10, we must multiply it by 10 3 times (also shown as 10³) which gives us 2.12.
To get back to the original value, we multiply this by . This gives us our answer.
This graph is a correct representation of the given quality! What I did was plug it into this online graphing calculator called desmos, you can use that!!
Answer:
13 hours
Step-by-step explanation:
You would divide 143 and 11 to get 13, then you multiply 13 and 11 to check your answer.
