Answer:
HI,
Answer A
Step-by-step explanation:
The rectangle has a length s - 6 and width s + 8 in terms of the side length s of the square.
The length of the sides of a square is s inches. The rectangle is six inches shorter and eight inches wider than the square. To express the length and width of the rectangle as a function of the side of the square:
Length of the rectangle = Length of the square - 6 = s - 6
Width of the rectangle = Width of the square + 8 = s + 8
Therefore, the correct expression for the length and width of the rectangle is: a) Rectangle width is s + 8 and length is s - 6

Write and simplify a function P that represents the profit made from selling x bracelets.
How many bracelets must the company sell to break even?
Keep answer simple
Answer:
the company must sell 15 bracelets to break even.
Step-by-step explanation:
To find the profit made from selling x bracelets, we need to subtract the cost of producing x bracelets from the revenue earned from selling x bracelets.
The cost of producing x bracelets is given by the function C(x) = 180 + 8x.
The revenue earned from selling x bracelets is given by the function R(x) = 20x.
To find the profit, we subtract the cost from the revenue: P(x) = R(x) - C(x).
Substituting the given functions:
P(x) = 20x - (180 + 8x).
To simplify the expression, we combine like terms:
P(x) = 20x - 180 - 8x.
Simplifying further, we combine the x terms and the constant terms:
P(x) = 12x - 180.
So, the function P(x) represents the profit made from selling x bracelets: P(x) = 12x - 180.
To find the number of bracelets the company must sell to break even, we set the profit (P(x)) equal to zero, since profit is zero at the break-even point:
12x - 180 = 0.
Adding 180 to both sides of the equation:
12x = 180.
Dividing both sides by 12:
x = 15.
Answer:
x/8 -1
Step-by-step explanation:
We know that if Two Complex Numbers (p + qi) and (a + bi) are said to be Equal then (p = a) and (q = b)
Given : (2x + 5) + (1 - y)i = -3 - 4i
⇒ 2x + 5 = -3
⇒ 2x = -3 - 5
⇒ 2x = -8
⇒ x = -4
Option 2 is the Answer
2x + 5 + i - yi = -3 - 4i
2x - yi = -8 - 5i
2x = -8 - 5i - yi
2x = -8 -i(5-y)
2(-4) = -8 -i(5-y)
0 = -i(5-y)
0 = 5 - y
-y = -5
y = 5
If x = -4, y is a real number.
