Answer:
2x^4-11x^3+68x-80
2x^4-4x^3-7x^3+14x^2-14x^2+28x+40x-80
2x^3(x-2)-7x^2(x-2)-14x(x-2)+40(x-2)
(x-2)(2x^3-7x^2-14x+40)
(x-2)(2x^3-4x^2-3x^2+6x-20x+40)
(x-2)(2x^2(x-2)-3x(x-2)-20(x-2))
(x-2)(x-2)(2x^3-3x-20)
(x-2)(x-2)(2x^2+5x-8x-20)
(x-2)(x-2)(x(2x+5)-4(2x+5))
(x-2)(x-2)(2x+5)(x-4)
(x-2)^2(2x+5)(x-4)
The answer is 7 because if you look at the bigger triangle you can see that all the numbers can be divided by 9 and on the smaller one you can see the answers to what was divided by 9. So ?=7
I mean if you add 3.5 7 times it’s 24.5, which it’s the closest number. It’s like multiplying 3.5 times 7, the result would be 24.5
Answer:
Width = 11.7 feet (To 1 decimal place)
Length = 23.5 feet (To 1 decimal place)
Step-by-step explanation:
w = Width
2w= Length
Area of rectangle = length * width
2w * w = 276
(Simplify expression)
2w² = 276
(Divide both sides by 2)
w² = 138
(Square root both sides to isolate w)
w = √138
w = 11.7473401245
w = 11.7 feet ( 1 decimal place)
2 ×11.7473401245 = 23.4946802489
Length = 23.5 feet (To 1 decimal place)
