Answer:
x = 7
Step-by-step explanation:
The triangles are similar, and they have a scale factor of 1/7 because 14 / 7 = 2.
Following the scale factor, you divide 49 by 7 to get 7.
Answer:
5+(-5)=0
-2+2=0
Step-by-step explanation:
Answer:
Step-by-step explanation:
f(x)= 3x+1 and g(x)= x^2 - 6
we need to find (f*g)(x)
(f*g)(x)= f(x) * g(x)
Plug in the given f(x) and g(x)
Apply FOIL method to multiply it
Cosα=x/L
L=x/cosα, we are told that the ladder base is 48 ft from the base of the wall and α=39° so:
L=48/cos39 ft
L≈61.76 ft (to nearest hundredth of a foot)
