If a = 3 and b = 5.what is the value of a2 + b2?

16

Step-by-step explanation:

If you replace the variables with what they equal and multiply then you should get 6+10 which equals 16.

The answer I received for your equation is 16

Step-by-step explanation:

Step 1) Replace your variables with the given number and rewrite your problem:  3 * 2 + 5 * 2 = __

Step 2) Solve from left to right: 3 * 2 = 6 , 5 * 2 = 10

Step 3) Add your two answers: 6 + 10 = 16

Your final answer should be 16.

Hope I helped, Good luck in your future studies :)

-A

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
