Which of the following groups of measurements will form a triangle? a 3 in., 10 in., 15 in.
b 5 in., 7 in., 10 in.
c 2 in., 15 in., 20 in.
d 3.5 in., 3.5 in., 7 in.

non of the above

in a 3² + 10²=109 which is not the square of 15in

b 5² + 7²=74 which is not the square of  10 in

c2² + 15²=229 which is not the square of 20 in

d 3.5² + 3.5²=24.50 which is not the square of 7

Step-by-step explanation:

answer: 4

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
