A parallelogram has a base of 9 feet and a height of
feet.
What is its area?

the answer is 9h

Step-by-step explanation:

since the other side has no length we cant solve it

but we can make it a variable

base=9 height=h

9*h=9h

b). 4320 have a nice day

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
