Areas of paralleolgrams and triangles?

The area of parallelogram is

.

If base has length 9.9 in and height has length 5.5 in, then the area is sq. in.

When base has length 11 in and height is unknown h, then .

Since the area is 54.45 sq. in., then

in.

h=4.95 in.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
