Answer/Step-by-step explanation:
Given that a and b are two corresponding sides of two similar figures, it follows that the ratio of their areas = a²/b².
We would use the above knowledge to solve the questions given as follows:
✔️The first pair similar of shapes:
Missing area = x cm²
Therefore,
x/9 = 8²/4²
x/9 = 64/16
x/9 = 4
Cross multiply
x = 4 × 9
x = 36 cm²
✔️The second pair similar of shapes:
Missing area = x cm²
Therefore,
x/240 = 8²/32²
x/240 = 64/1,024
Cross multiply
x*1,024 = 64*240
x*1,024 = 15,360
Divide both sides by 1,024
x = 15,360/1,024
x = 15 cm²
✔️The third pair similar of shapes:
Missing area = x cm²
Therefore,
x/40 = 3²/2²
x/40 = 9/4
Cross multiply
x*4 = 9*40
x*4 = 360
Divide both sides by 4
x = 360/4
x = 90 cm²

Answer:
Th best thing would be 35% off or the blue coupon
Step-by-step explanation:
Well we can solve the orange coupon first which would be 540.37 for the final price
the blue coupon is 35 percent off or we can just multiply 815.37 by 0.65 becuase since its “off” you would only have to pay 65 percent of the item which is why I’m multiplying by 0.65. You would end up with something like 529 something which is less than 540.37
The blue coupon would be best

The sum of the polynomials is 4x² - 12y² - 11x. The correct answer is an option (D) 4x² - 12y² - 11x.
What is a polynomial?
A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.
The polynomials are given as follows:
(8x² - 9y² - 4x) + (x² - 3y² - 7x)
By combining like terms, we can add the polynomials:
(8x² - 9y² - 4x) + (x² - 3y² - 7x)
= 8x² - 4x² - 9y² - 3y² - 4x - 7x
= 4x² - 12y² - 11x
Therefore, the sum of the polynomials is 4x² - 12y² - 11x.
Hence, the correct answer is option (D) 4x² - 12y² - 11x.
