Pema is trying to figure out why (-5)×(-2)=+10. He knowa these three things:
•5+(-5)=0
•5+(-5)×(-2)=[5×(-2)]+[(-5)×(-2)]
•5 ×(-2)=(-10)
How can pema use what he knows I to figure out that (-5)×(-2)=+10?

Help me guys need the ans before 7:00am tomorrow.

i belive those are the ones that are under 90 degreese.

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

b.

step-by-step explanation:

i just know

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
