Let the width = x
=>length = 2x-1
91= x(2x-1)=2x^2-x
2x^2-x-91=0
=(2x+13)(x-7)
=> x=-13/2=> no
=>x= 7 cm
Answer:
Step-by-step explanation:
Answer:
-13
Step-by-step explanation:
Plug in 10 as x into the function:
f(x) = -2x + 7
f(10) = -2(10) + 7
f(10) = -20 + 7
f(10) = -13
So, f(10) = -13
The answer of g(x) =|x+2|-1 is X1 =-3, X2=-1
