B. 54 meters
first you want to set up your ratios and cross multiply to figure out the number to square l's ratio. which would be 10.8.
then use formula for perimeter
2(l)+2(w)=9
2(10.8)+2(18)=53.6-rounded =54<span />
Lets solve for x. So first lets distribute.
Now lets put x on one side and combine like terms
EDIT: whoops clicked on answer
-15x=21
x=-21/15
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Both the first and second signs are negative,
Let α and β are the roots of the ,
then, we know that the relationship between the zeroes and coefficients of quadratic equations:
Since the product of roots is positive.
So, the signs of the factors will be one positive and one negative.
Hence, Option 'D' is correct.
Answer:
It's an equilateral triangle so the measure of each angle here=60 degrees
s..4x degree=15*4
hence, the value of X=15

Answer:
so the transitive property can be invoked in step 9
Step-by-step explanation:
Without the figure, it is difficult to tell what these steps do. However, the symmetry of the proof suggests that step 4 can match step 8, and its Reason can be "deduced from steps 2 and 3."
The idea of steps 4 and 8, taken together, is to show that DC and DB are both equal to DA, so the transitive property can be invoked in step 9.
