Answer:
Step-by-step explanation:
BD=BL(given)
so ∠BLD=∠BDL=3x
90+∠GBD+30=180
∠GBD=180-120=60°
Also ∠GBD=∠BLD (given)
so ∠BDL=60°
3x=60
x=20°
Answer:c. F(2)=g(-2)
Step-by-step explanation:
<span>Use a table of function values to approximate an x-value in which the exponential function exceeds the polynomial function. f(x) = 3(4)(2x-4). h(x) = (x + 2)3 + 1.
