Answer:
C
Step-by-step explanation:
The big triangle and small triangles are similar so their corresponding sides are in proportion.
x/15 = 15/9
x= 15*15/9
x=25

so, no breaks on the denominator thus, the LCD will be all three then.
Point A, because the square root of 81 is 9, and 83 is just slightly larger than 81. Point A is slightly more than 9, and all of the other points are out of range, so the answer is A
I am not sure but i think you were to say this:(1st quality)x=( )(2nd quality)
Answer:
One solution
Step-by-step explanation:
Lets solve it for b
3b= -6a+12
3b= 6a-12
Simplifying
b= -2a+4
b= 2a+4
Both have same slope and intercept hence both lines are going to intersect at one point. So the equations are having one solution.
