Answer:
B=10
Step-by-step explanation:
It's a perfect square of equation ax²+2abx+b²
I'm the given equation a is 1 and b is 5 so 2(a)(b)=2(1)(5)=10
(ps: when I say b in the explanation I mean another b not the one in question as to not be confused)
17, because 9 + 8 = 17.
17 - 8 equals 9
Answer:
The answer is B, f(x)=5(2/5)^(z)
Step-by-step explanation:
I did the graphs for all of them and graph B was identical to the one in the picture.
First, you need to use the distributive property and distribute the 2 inside the parentheses.
2(x + 1) + 3x = 17
2(x) + 2(1) + 3x = 17
2x + 2 + 3x = 17 -Combine like terms
2x + 3x + 2 = 17
5x + 2 = 17 -Subtract 2 from both sides of the equation.
5x + 2 - 2 = 17 - 2
5x = 15 -Finally, divide each side by 5 to find your answer
5x/5 = 15/5
x = 3
Hope this helps you!
