If x =7 and y=10 evaluate the following x²+7xy²-6yx²+7x+ 15

Answer»

Answer:

2073

Step-by-step explanation:

x²+7xy²-6yx²+7x+ 15

substitute x =7 and y=10 in the above EQUATION, we get

7²+7(7)(10)²-6(10)(7)²+7(7)+ 15

= 49 + 49*100 - 60*49 + 49 +15

= 49 + 4900 - 2940 + 49 +15

= 5013 - 2940

= 2073
