I don't know, Sorry, but I will keep looking at it to see if I can figure it out, Sorry
yes because you would subtract -9 from both sides of the equation leaving you with x = -4
Answer:
The measure of the sides is 20 cm.
Step-by-step explanation:
Opposite side of a parallelogram:
Opposite sides of a parallelogram are congruent, that is, they have the same measure.
Measures (2x+10) cm and (x+15) cm:
This means that:



2x + 10 = 2*5 + 10 = 10 + 10 = 20
The measure of the sides is 20 cm.
6) x= 2, angle = 90 degrees obviously
7) Im not sure on this one
8) x = 5
9) x = 1
Answer:
128,8,28,36
Step-by-step explanation:
if u multiply 32 times 4 u get 128 but if u subtract them u get 28
but if u divide them then u get 8 but if u also add them u get 36
