5x^2+60x=0
x(5x+60)=0
x=0
and
5x+60=0
5x=-60
x=-12
therefore, the first option is correct
Answer: 12 3/8
10 1/2 + 10 1/2= 21
45 3/4 - 21 = 24 3/4
24 ÷ 2 = 12
Change the 3/4 into 8ths = 6/8
Divide that in half which gives you 3/8
So the length is 12 3/8
Answer:
5.1
Step-by-step explanation:
Since there is no diagram provided here, we assume that c is the length of the hypotenuse, so we have ...
c² = a² +b² . . . . . . Pythagorean theorem
c² = 2.7² +4.3² = 25.78
c = √25.78 ≈ 5.0774
c ≈ 5.1
