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

Answer:
D is correct
Step-by-step explanation:
A graph of that sort will make a perfectly mirrored "V" shape, and with no offset, the bottom point will be on the y axis. This means that the first equation will intercept the y axis at zero, the second will intercept the y-axis at -15.
"A" may seem correct also, as the second graph will intercept the x-axis at -15, but it is not complete, as it will intercept that axis at +15 as well.
Answer:
B
Step-by-step explanation:
Answer:
875
Step-by-step explanation:
lets assume the original amount X
the new amount = X - ( X × 40% )
525 = (60 × X) ÷ 100
X = ( 525 × 100 ) ÷ 60
<u>X = 875</u>
