Answer:
Step-by-step explanation:
g(5)= (-5)^2 + 5(-2) - 4
25 - 10 - 4
15 - 4 = 11
f(11)= (11)^2 + 2(11) + 3
121 + 22 + 3
143 + 3 = 146
Well you can combine the 2 equations, so it will be -2x+7y=6 now move the -2x to the other side so 7y=2x+6, now divide everything by 7. y= 2x/7 + 6/7.
X=2rad10
y=4rad5
it’s a 45-45-90 triangle so the two legs are the same. the equation for hypotenuse would be h=rad2 x leg. substitute; h=rad2 x 2rad10 = 4rad5
