Lucy has been asked to construct as many unique triangles as she can that have all sides of integer length, one side of length 7 cm, and a perimeter less than or equal to 20 cm. Find the number of unique triangles, isosceles triangles, and triangles with perimeter exactly equal to 20 cm that Lucy can construct. A.
23 unique triangles, 8 isosceles triangles, and 2 triangles with perimeter equal to 20 cm
B.
21 unique triangles, 9 isosceles triangles, and 3 triangles with perimeter equal to 20 cm
C.
19 unique triangles, 7 isosceles triangles, and 4 triangles with perimeter equal to 20 cm
D.
22 unique triangles, 10 isosceles triangles, and 3 triangles with perimeter equal to 20 cm

i think 5 miles per hour

step-by-step explanation:

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less

step-by-step explanation:

p = 6s

step-by-step explanation:

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
