He will be making a right triangle with the legs being 24 x 45. The diagonal will be the hypotenuse of the triangle. To find the amount of fencing we need the perimeter of the triangle.
Use Pythagorean theorem to find the length of the hypotenuse.
a^2 + b^2 = c^2
24^2 + 45^2 = c^2
576 + 2025 = c^2
2601 = c^2
sqrt 2601 = c
c = 51
Adding the three lengths the total fencing needed is
51+24+45=120 meters
The expression representing this would be 24 × 50 × 2. You do not need parentheses because multiplication is commutative. Simplified this would then be 100 × 24 which is $2400 .
The correct factorization is
2(x-2)²
The problem 10bf + 25bg – 21p – 14pq cannot be factored because it cannot be simplifed further. This is because there are no common factors between in any of the terms.
we have given y interms of x.
we have given that add 2 to x.
which means 
so we have
