Answer: b
Step-by-step explanation:
You know the formula of a triangle is: (base*height)/2
So: 4*8=32
32/2=16cm^2
Since its a parallelogram, you could say that there are two of these triangles, so: 16*2=32cm^2
Now we're left with the part in the middle. The sides are now 8 by 8 because we took away 4 from 12, so: 8*8= 64cm^2
Now you just add all your values together, so: 32+64=96cm^2
Answer:
16 = 2x
Step-by-step explanation:
The pattern for a direct variation equation is y = kx
y is the "output" or result
k is the "constant" a number that doesn't change in the equation.
x is the "unknown" variable that makes the output of the equation true when found.
Here x=8
16 = 2(8)

Step-by-step explanation:
NOOOOO
Im not really sure if im right but i think the answer is 140-
Explanation:
I added 30+10 which equalled 40 and then i noticed the circle which would equal 360 and subtracted it from the 40 however that got me more then i needed since it wasnt one of the choices. Then i thought hmm maybe its a supplementary angle which usually equals 180 so i subtracted it from 40 which got me 140! Like i said i dont know if im right or not :(
The sum of the adjacent angles of a parallelogram is always equal to 180°.
So we know that
.
When we simplify that expression:
Isolate the y by divide both sides by 3:
