$ax^2+ay^2-bx^2-by^2+b-a$
= $a(x^2+y^2)-b(x^2+y^2)+b-a$
= $(x^2+y^2)(a - b)+b-a$
= $(x^2+y^2)(a - b)-(a - b)$
= $(a - b)(x^2+y^2 -1)$

I need help with 14 and 15!?

Levart [38]

Answer:

Step-by-step explanation:

Pythagorean theorem states that the hypogenous of a right triangle is $c=\sqrt{a^{2}+b^{2}}$ . The hypogenous is the longest part of the triangle which is directly across from the 90 degree angle.

a = 9

b = 12

so,

$c = \sqrt{9^{2}+12^{2} } = 15$
