Answer:
x=1 and x=-1/3
Step-by-step explanation:
By the zero product property, we have two separate equations, x-1=0 and 3x+1=0
x-1=0
x=1
3x+1=0
3x=-1
x=-1/3
So x=1 and x=-1/3
Hope this helped!
Step-by-step explanation:
When a number is multiplied by 5, the last digit of the product must be 0 (mod 5).
=> Last digit = 0 or 5.
Since 0 is not an option here, the answer must be 5. (C)
B. I think I’m really not sure that’s confusing as hell and I’ve passed that
Answer:
3/5
Step-by-step explanation:
Sin is opp/hyp so it would be 30/50 in lowest form it would become 3/5
Answer:
b and c
Step-by-step explanation:
The Triangle Inequality Theorem lets us know that the sum of the two shortest sides of the triangle must be greater than the third side of the triangle.
In both A and D, the sum of the shortest two sides are equal to, not greater than the third side, so they will not form a triangle.
In B, 12+20 is 32, which is greater than 25. And in C, 18+24 is 42, which is greater than 30, so they both will form a triangle.
