Draw a rectangle with an area of 42 square units
Butoxors [25]
We know, Area = Length * Width

So, with area 42, dimensions could be: 1 * 42
2 * 21
3 * 14
6 * 7

Just draw the lines with that measures, two pair of two equal opposite lines.

Hope this helps!

7. Expand and reduce A(x). Then calculate A(x) for x=1.<br> A (x) = (3x – 3)(3x + 2)
SashulF [63]

Given:

The function is

A(x)=(3x-3)(3x+2)

To find:

The simplified form of A(x) and value of A(x) at x=1.

Solution:

We have,

A(x)=(3x-3)(3x+2)

A(x)=(3x)(3x)+(3x)(2)+(-3)(3x)+(-3)(2)

A(x)=9x^2+6x-9x-6

A(x)=9x^2-3x-6

Putting x=1, we get

A(1)=9(1)^2-3(1)-6

A(1)=9-3-6

A(1)=9-9

A(1)=0

Therefore, the simplified form of A(x) is A(x)=9x^2-3x-6 and the value of A(x) at x=1 in 0.
