Answer: it equals 1
Step-by-step explanation:
The sign of the product would be the postitive sign because all three integers have the same sign.
The mode is the number that occurs most frequently in the set.
Putting the numbers in order will help us find the mode.
18,18,21,24,24,24,27,30,30,30
We see that 24 and 30 have an equal number of occurrences in the data set, meaning that 24 and 30 are both modes.
X = 10
The triangles are similar by SAS, so we can set up a proportion of their sides.
9/(33-9) = 12/(3x+2)
9/24 = 12/3x+2
Reduce
3/8 = 12/3x+2
Cross multiply
3(3x+2) = 12*8
Distribute and multiply
9x + 6 = 96
Subtract 6
9x = 90
Divide by 9
x = 10
Check:
9/24 = 12/3x+2
9/24 = 12/3*10 + 2
9/24 = 12/30 + 2
9/24 = 12/32
3/8 = 3/8 :)
Answer:
9x-1
Step-by-step explanation:
The perimeter of the triangle is adding up all 3 sides.
(3x)+(x+6)+(5x-7)=P
9x-1 = perimeter
All I have done is combine like terms.
If there is a... x = something, replace x with the number.
