Answer:
72.1 and -48.1
Step-by-step explanation:
I set up the equations x + y = 24 and x*y=-3468. Then I substituted for y and used the quadratic formula to come to two numbers rounded to about 72.1 and -48.1. Hope that helps :)
when a=4 and b=3,
3.14((4 x 2)+ (4 x 3)) = 3.14(8+12) = 3.14 x 20 = 62.8

Step-by-step explanation:
Answer:
a) x = -1 and y = -10
Step-by-step explanation:
The first part says find the value of y when the value of x is -3. Then the second part of the question is to find the value of x when the value of y is 2.
so lets solve part a)

So answer to part a is x = -1 and y = -10
similarly try the other parts.
