PLEASE HELP ASAP
Lerok [7]

Answer:

A) 2(9x - 2)

Step-by-step explanation:

The greatest common factor of 18x and -4 is 2.

B is wrong because 18 is not the greatest common factor of both, since 4 cannot be divided by 18 and result in a whole number.

C is wrong because 18x cannot be divided by 4 to produce a whole number.

D is wrong because it restates the problem in a different way, therefore not factoring it completely. 1 is a common factor of both, but not the greatest.

What is the area of the composite figure? 262 cm2 264 cm2 266 cm2 268 cm2
miv72 [106K]

The Area is a two-dimensional scalar quantity. The area of the composite figure is 264 cm².

<h3>What is the area?</h3>

The area of a two-dimensional region, form, or planar lamina in the plane is the quantity that represents its extent. On the two-dimensional surface of a three-dimensional object, the surface area is its counterpart.

The composite figure can be broken down into four parts a square(A), a triangle(B) and two rectangles(C and D).

Now, if the area of the composite figure is taken out it will be,

\text{Area of composite}=\text{Area of Square A} + \text{Area of triangle B} + \text{Area of Rectangle C} + \text{Area of Rectangle D}\\

\text{Area of Composte}=(10^2)+(\dfrac12 \times 6 \times 4)+(8 \times 4)+(20 \times 6)\\\\\text{Area of Composte}= 100+ 12 + 32 + 120 =264\rm\ cm^2

Thus, the area of the composite figure is 264 cm².
