Answer:

Qn1: -37

Qn2: 16

Qn3:-33.6

Step-by-step explanation:

Qn1:

k(4) = -4*4-6 = -16-6 = -22

m(5) = (5^2)-8*5=-15

k(4)+m(5)= -22+ (-15)= -37

Qn2:

m(-2)= 4 -8*(-2)= 20

n(10) = 2 -6 = -4

20+ (-4)=16

Qn3:

n(-100)= -20-6 = -26

k(-8) = -1.6 -6= -7.6

-26+ (-7.6) = -33.6

The difference between the square of two numbers is 11. Twice the square of the first number increased by the square of the seco

jeyben [28]

Answer:

Below in bold.

Step-by-step explanation:

x^2 - y^2 = 11

2x^2 + y^2 = 97

From the first equation:

y^2 = x^2 - 11

Substituting in the second equation:

2x^2 + x^2 - 11 = 97

3x^2 = 108

x^2 = 36

x = 6, -6.

Substituting for x in the first equation:

(6)^2 - y^2 = 11

y^2 = 36 - 11 = 25

y = 5, -5.
