The answer is 76.

2 times 5 is 10. There are two sides so 10 times 2 is 20.

4 times 5 is 20. There are two sides so 20 times 2 is 40.

4 times 2 is 8. There are two sides so 8 times 2 is 16.

20+40+16 is 76.

Answer:

(a) Rule: Multiply the input (x) by 2 and add 5 to the result of the product

(b) $y =2x +5$

Step-by-step explanation:

Given

The attached table

Solving (a): The rule of the table in words

First, we calculate the slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Using:

$(x_1,y_1) = (2,9)$

$(x_1,y_1) = (10,25)$

So, we have:

$m = \frac{25 - 9}{10 - 2}$

$m = \frac{16}{8}$

$m=2$

The equation is calculated using:

$y - y_1 =m(x - x_1)$

Using:

$(x_1,y_1) = (6,17)$

We have:

$y - 17 =2(x - 6)$

$y - 17 =2x - 12$

Make y the subject

$y =2x - 12+17$

$y =2x +5$

Hence, the rule is:

Multiply the input (x) by 2 and add 5 to the result of the product

(b): The rule, in algebra

As solved in (a), the rule is:

$y =2x +5$

Verdich [7]

Answer:

Step-by-step explanation:

Divide so you get a decimal. 1/2 = 0.5. 2/3 = 0.666

0.666 > 0.5

So 1/2 is less than 2/3
