Jared needs to create a right triangle to add support to the side of this farm. He buys 3 pieces of wood of length 8 ft, 11 ft, and 15 ft. Did Jared pick the correct sizes in order to create a right triangle, and why?

Yes. 8^2+112=152Yes. 8 squared plus 11 squared is equal to 15 squared

Yes. 8+11>15Yes. 8 plus 11 is greater than 15

No. 8^2+112≠152No. 8 squared plus 11 squared is not equal to 15 squared

No. 8+11>15No. 8 plus 11 is greater than 15

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
