Which two intergers is
between

options: -13 and -12 or - 11 and - 10 or and - 10 and -9 or -14 and -13.

​

So, the reason a triangle has an area of bh/2 is because it's half a rectangle. Draw a diagonal across a square and you have to right angles.

a2 + b2 = 1102

Hey, since it's a square, a and b are the same.

2a2 = 12,100

a2 = 6050

a = √6050 = 77.78 m

The area is given above, 6050 m2.

answer: idk

step-by-step explanation:

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
