Which of the following equations has infinitely many solutions?
A. 5(x+5)+2=10x+5(x+2)
B. 5x+2=2x+10
C. 5x+5=2
D. 5x+5(2x+10)=15x+50

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
