A piece of wire 10 cm long is bent to form a right-angled triangle.
The two shorter sides have lengths of x cm
and 2x cm respectively.
(a) Form an equation in x and show that it
reduces to x2 - 15x + 25 = 0.
(b) Hence find the length of the longest side.

Jonathan pays $1.90 per pound for potatoes. he buys 8.3 pounds of potatoes. he determines that he will pay $15.77, before tax, for the potatoes. which best describes the reasonableness of jonathan’s solution? jonathan’s answer is reasonable because there are two decimal places in the factors and two in the product. jonathan’s answer is unreasonable because there are three decimal places in the factors and two in the product. jonathan’s answer is reasonable because is 16, and 16 is close to 15.77. jonathan’s answer is unreasonable because is 8, and 8 is not very close to 15.77.
