(x+1)(x-5)= 2^4=16
x^2 -4x -5 =16
x^2-4x-21=0
x= -3 or 7
but we would choose 7 as the answer as -3 gives negative value at (x+1) and we know that log of negative number is not defined.
Triangle ABC is similar to triangle ADE.
The scale factor from ADE to ABC is 2. We know this because two of the sides on the triangle are equally divided into 2.
29(2) = 58
BC = 58
Answer: Either A or B
Step-by-step explanation:
Both A and B are the same answers, but the main answer should be
c+d=17, 4c+2d =54
C represents the number of cows and D represents the number ducks. The two and fours in front of the variables represents the number of legs the repesctive animal has.
c+d would mean how many animals are in the barn. Feel free to clarify the two same answers
