Answer:
4 cm
Step-by-step explanation:
Perimeter of a parallelogram is 2b+2h=30 where b is base and h is height.
if AD is 3cm more than twice AB, then it's 3+2x where x is length of AB.
Input this into the perimeter equation: 2(3+2x)+2(x)=30
Simplify to get 6+6x=30
x=24/6=4
Answer is 4 cm.
2x-6=90 would be the answer
Answer:
A and B
Step-by-step explanation:
-3 and -2 are the only values less than or = to -2
the rest are greater than -2
50?
I'm assuming 50 because the angles to a triangle always adds up to 180 and this one has 130 and 130+50=180
