(polynomials and factoring) WILL GIVE BRAINLIEST PLS I NEED AN EXPLANATION. how do you get the answers pls explain, extra points + brainliest for best explanation

Vâng, câu trả lời được liên kết với hệ số e, g nếu bạn nhìn vào 2x 1/3 hệ số là gì? Chính xác là nó là 2, vì vậy bạn thay thế nó bằng các yếu tố hàng đầu của nó sẽ là 64

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).
