Answer:
using quaderatic expression solving problems of algebraic expressions.
Step-by-step explanation:
no1.
take the smallest side to be x
and the longest side to be x-1/3
then expand the expression equating to 30.
then solve for x value
K is equal to -69.5 K=69.5 You put it in an equation 47.9-K=-21.6Then you subtract 47.9 from both sides and you get K=69.5
The correct answer is C
Explain
The graph is given
F(x) is given -2^x
By putting x= - 3 in the first equation
G(x) = -9
Which is false
by putting x= -3 in the second equation
g(x) is also equal -9
Which is false
Hope this help you :D
