Answer:

Part A: 12c sq. m

Part B: 6 sq. m

Step-by-step explanation:

Area of a rectangle = l X b sq. units

Part A:

Given Length , l = 6c units.

And Breadth, b = 2 units.

Hence, the area = 6c X 2 sq. units

Area, A = 12c sq. units

Part B:

When c = $\frac{\textbf{1}}{\textbf{2}}$

From Part A, we have Area, A = 12c sq.units

When c = $\frac{1}{2}$ , area = $12 \bigg ( \frac{1}{2} \bigg )$ sq. units.

Therefore, Area = 6 sq. units.

An=an−1−4 a1=15 to explicit formula

USPshnik [31]

Answer:

$a_n=3n-12$

Step-by-step explanation:

We are given the recursive formula:

$a_n=a_{n-1}-4, a_1=15$

This is the recursive formula for an arithmetic sequence.

The explicit formula for an arithmetic sequence is given by:

$a_n=a_1 + d({n-1} )$

Where d=3 is the common difference.

We plug in this values to get:

$a_n=15 + 3({n-1} )$

We now expand and simplify to get:

$a_n=15 + 3n-3$

We simplify to obtain:

$a_n= 3n-12$

What is the answer to this

olasank [31]

Three times the variable m minus four is equal to fourteen.

Another way could be:

Four less than three multiplied by m is equivalent to fourteen.

The first way I put it is simpler but if you really want to impress your teacher then I suggest going with the second way.

Also if you are looking to solve the equation then it would be:

3m - 4 = 14

+4 +4

------------

3m = 18

----- -----

3 3

m = 5

Hope that helped :-)
