Answer:
1 3/4 or 7/4 or 1.75
Step-by-step explanation:
Answer:
= 6x² + 24x + 17
Step-by-step explanation:
g(x+2) = 6(x+2)² -7
= 6(x² + 4x + 4) - 7
= 6x² + 24x + 24 - 7
= 6x² + 24x + 17
Answer: 30 dominoes in total.
Step-by-step explanation:
Each line is 21 inches long.
the space between dominoes is 1 + 1/2 inches.
(assuming that the distance includes the domino itself) Now, we need at least two dominoes to see this distance,
The we have N + 1 dominoes per line, and the distance is:
N*(1 + 1/2)inches = 21 inches
If we find N, we can find the number of domineoes in each line:
N = 21/(1 + 1/2) = 14
This means that we have 14 + 1 = 15 dominoes in each line, and we have two lines, so we have 30 dominoes in total.
Answer:
2
Step-by-step explanation:
2/3÷1/3
Changing the divide sign into multiply will invert the term after it
So we get
(2/3)*3
(2*3)/3
We get
2
2x + x = 180
This is because 2x is on one side while x is on the other, if those two angles add up they must add up to 180 because the two angles form a 180 degree angle or just a straight line
2x + x = 180
3x = 180
x = 60
