The ratio of the number of miles covered by car a to the number of miles covered by
car b is 1 t0 4.
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:
28 feet
Step-by-step explanation:
We know that the perimeter of a square is 
, where l is the length and w is the width.
We also know that the perimeter of a triangle is all of its sides added up.
Since the perimeters will be equal to each other, we can make both of these statements an equation that are equal to each other.
Basically:
We can combine like terms to get a <em>less scary</em><em> </em>equation.
Our goal is to now isolate x so we can find it's value.
Add 2 to both sides:
Subtract 6x from both sides:
Add 10 to both sides:
Divide both sides by 2:
Now we know the value of x, however, our work isn't done. They want to know the perimeter, so we need to substitute x in as 5.
Let's do it on the triangle.
(remember, this is our simplified version of the triangle)

Answer:
A -a linear relationship showing as height increases, shoes size increases.
Step-by-step explanation:
The answer is C.
It’s C because if you add the marble back to the bag you have a 4:5 chance of adding the white marble again, hence giving you another white marble in the bag to pick
