The formula for the area of a parallelogram is A = bh, where b is the base and h is the height. A parallelogram that is not draw
Bezzdna [24]

Answer:

Option 2)  2x3 – 6x2 – 14x + 24 square centimeters

Step-by-step explanation:

We know the Parallelogram Area is given by

A=bh      Eqn. (1)

where

b : is the base

h  : is the height

We are also given that the base is

b=2x^2+2x-6

and the height is

h=x-4

So we can plug these two expressions in Eqn. (1), simplify and find our Area equation as follow:

A=(2x^2+2x-6)(x-4)\\\\A=(2x^2)(x)+(2x)(x)-(6)(x)+(2x^2)(-4)+(2x)(-4)-(6)(-4)\\\\A=2x^3+2x^2-6x-8x^2-8x+24\\\\A=2x^3+2x^2-8x^2-6x-8x+24\\\\A=2x^3-6x^2-14x+24

Which matches Option 2. from the available ones.

The sum of two angles in a triangle totals 62.5 degrees. What is the other angles measure?
Advocard [28]
**All 3 angles of a triangle have a sum of 180°.**

So if 2 of those 3 angles are 62.5°, you would just subtract that by 180°.

180 - 62.5 = 117.5

The third angle would have to be 117.5°.
