Answer:
Step-by-step explanation:
you started by expanding the bracket 3(2x+6) became 6x+18.\
Then you rearranged the equation so like terms were together.
You put brackets around the like terms so (27+18)+(6x+2x)
You added the first like terms (27+18)= 45
then you added the second like terms (6x+2x)= 8x
124 because snakes don’t have legs and since cats and dogs have 4 legs each 23x4=92 and 8x4=32. 92+32=124
Answer:
C. 16
Step-by-step explanation:
The distance between two points on the number line is the absolute value of the difference of their coordinates.
If the coordinates of two points on the number line are a and b, then the distance between the two points is
d = |a - b|
The coordinates here are -9 and 7.
distance = |-9 - 7| = |-16| = 16
The inscribed circle has its center at the point of intersection of the angle bisectors, which also happen to be the medians. Hence the altitude of the triangle is 3 times the radius, or 12 inches.
The side length of this triangle is 2/√3 times the altitude, so the area is
... Area = (1/2)·b·h = (1/2)·(24/√3 in)·(12 in)
... Area = 48√3 in² ≈ 83.1384 in²
