Mathematics

We are told to factor the expression ax + ay + bx + by. To factor the given expression, we must use grouping. The first step is to grouping is to 'group' the expression into two different binomials. This results in (ax + ay) + (bx + by). From the first binomial, we can factor out a. From the second, we can factor out b. After doing this, we get a(x + y) + b(x + y). We immediately notice that there are two like terms, (x + y). We can group the two remaining terms together to get (a + b). When we put the two terms together, we get (a + b)(x + y). Therefore, the factored version of ax + ay + bx + by is (a + b)(x + y). Hope this helped!

Ax + ay + bx + by
= (ax + ay) + (bx + by)
Use the Distributive property
a(x + y) + b(x + y)
Use the Distributive property again
(a + b)(x + y)

Have an awesome day! :)

Calculus A hard problem help please
dexar [7]
∑x = 1 + 2 + 3 + 4 + 5 + 6 = 21
∑y = 8 + 3 + 0 + 1 + 2 + 1 = 15
∑x^2 = 1 + 4 + 9 + 16 + 25 + 36 = 91
∑y^2 = 64 + 9 + 0 + 1 + 4 + 1 = 79
∑xy = 8 + 6 + 0 + 4 + 10 + 6 = 34

r = (n∑xy - ∑x∑y)/(sqrt(n∑x^2 - (∑x)^2)*sqrt(n∑y^2 - (∑y)^2)) = (6(34) - 21(15))/(sqrt(6(91) - (21)^2)*sqrt(6(79) - (15)^2)) = (204 - 315)/(sqrt(546 - 441)*sqrt(474 - 225)) = -111/(sqrt(105)*sqrt(249)) = -111/(10.25*15.78) = -111/161.7 = -0.68
