Question

multiply (x+7) and (y-5)​

Answer 1

Step-by-step explanation:

To multiply:-

(x+7)(y-5)

Used formula:-

• Distributive law

$\\ \sf\hookrightarrow (a+b)(c-d)=a(c-d)+b(c-d)$

Solution

$\\ \sf\hookrightarrow (x+7)(y-5)$

$\\ \sf\hookrightarrow x(y-5)+7(y-5)$

$\\ \sf\hookrightarrow xy-5x+7y-35$

$\\ \\ \therefore\sf (x+7)(y-5)=xy-5x+7y-35$

Answer 2

Step-by-step explanation:

(x + 7)(y - 5)

= x(y -5) +7(y-5)

= xy -5x + 7y -35
