log 2 (24 / 3) = log 5 (x)
log 2 (8) = log 5 (x)
log 2 (2^3) = log 5 (x)
3 × log 2 (2) = log 5 (x)

A) (2y – 7) units by (2y – 7) units
B) (4y – 49) units by (y + 1) units
C) (2y – 7) units by (2y + 7) units
D) (y – 7) units by (4y + 7) units
Answers
The dimensions of the rectangle are (2y – 7) units by (2y + 7) units
Area of a rectangleThe formula for calculating the area of a rectangle is expressed as
Area = length * width
Given the following parameter
Area = .4y² - 49
Factorize the area
Area = (2y)² - 7²
Using the difference of two square
Area = (2y - 7)(2 y + 7)
Hence the dimensions of the rectangle are (2y – 7) units by (2y + 7) units

Tony's class needs more than $500 for the school dance.
So far, they have raised $200. They plan to have a car
wash, charging $8 a car, to raise more money. Tony
solved the inequality 8x + 200 > 500, and determined
that if they wash 37 cars, they will have enough money.
Is he correct? Explain.
(Please reply with sample answer if there is one!!)
Answers
Answer:
yes hes correct.
Step-by-step explanation:
37x8=296. 296+200= 596. 596>500
Answer:
No, Tony is not correct. Solving the inequality tells us that x is greater than or equal to 37.5 Since the class must wash a whole number of cars, they need to wash at least 38 cars.

The Last two are on the negative side of the y-axis. B is the closest to zero as the wider the graph is, the lower the coefficient is.

Find the length of each diagnol and the area
Answers
Answer:
The length of diagonal BD is 11·(1 + √3)
The length of diagonal AC = 22
Step-by-step explanation:
The given data are;
Quadrilateral ABCD = A kite
The length of segment AD = 22
The measure of ∠DAE = 60°
The measure of ∠BCEE = 45°
Whereby, triangle ΔADE = A right triangle, and DE is the perpendicular bisector of AC, by trigonometric ratio, we have;
AE = EC
DE = 22 × sin(60°) = 11·√3
AE = 22 × cos(60°) = 11
∴ AE = EC = 11
BE = EC × tan(∠BCE) = 11 × tan(45°) = 11
The length of the diagonal BD = BE + DE (By segment addition property)
∴ BD = 11 + 11·√3 = 11·(1 + √3)
The length of diagonal BD = 11·(1 + √3)
The length of diagonal AC = AE + EC
∴ AC + 11 + 11 = 22
The length of diagonal AC = 22.
