whats another way to write (s-6)(s+1) when s represents the side of a square and the equation represents the area of a rectangle

viktelen [127]

The another way to write (s - 6)(s + 1) is s² - 5s - 6

Step-by-step explanation:

Let us revise how multiply two binomial (a + b)(x + y)

Multiply the 1st terms
Multiply the 2nd terms
Multiply the nears and extremes, where nears are the 2nd term of first bracket and 1st term in the second bracket, the extremes are the 1st term in the first bracket and the 2nd term in the second bracket
Add the like terms if necessary

∵ The area of the square = (s - 6)(s + 1)

- To find the another way multiply the two brackets

∵ s × s = s²

∵ -6 × 1 = -6

∵ -6 × s = - 6s ⇒ nears

∵ s × 1 = s ⇒ extremes

- The terms - 6s and s are like terms, then add them

∵ - 6s + s = - 5s

∴ (s - 6)(s + 1) = s² - 5s - 6

∴ The area of the square = s² - 5s - 6

The another way to write (s - 6)(s + 1) is s² - 5s - 6

1st transformation:
$A'=(-3,-4)\\
B'=(-7,-4)\\
C'=(-3,-8)\\
D'=(-7,-8)$

2nd transformation:
When you rotate a point around the origin by 180 degrees, you change both coordinates to opposite values.
$A''=(3,4)\\ B''=(7,4)\\ C''=(3,8)\\ D''=(7,8)$

Answer:

Between 21 years and 75 years

Step-by-step explanation:

Given that a real estate company is interested in the ages of home buyers. They examined the ages of thousands of home buyers and found that the mean age was 48 years old, with a standard deviation of 9 years.

X the ages of home buyers is N(48, 9)

a) $30\leq x\leq 66\\|x-48|\leq 18\\|x-48|\leq 2\sigma$
