Answer:
Multiples of 60
Step-by-step explanation:
If a a number finished with a 0, (unless it is 0) than it is divisible by 2 and 5.
If a number is divisible by 20 then it is divisible by 4. Finally if its divisible by 6 then it is by 3 too.
60 is the first number that satisfies all of the constraints and so does any of its multiples (up to 180 in this case)
Answer:
Step-by-step explanation:
The given expression is;
This implies that;
Equate the exponents;
Expand;
5sqrt(x+7)=-10
Dividing both sides by 5:
5sqrt(x+7)/5=-10/5
sqrt(x+7)=-2
Squaring both sides of the equation:
[sqrt(x+7)]^2=(-2)^2
x+7=4
x+7-7=4-7
x=-3
Replacing in the original equation:
5sqrt(x+7)=-10
5sqrt(-3+7)=-10
5sqrt(4)=-10
5(2)=-10
10=-10 It's not equal, then x=-3 is an extraneous solution
Answer: 42/11 = 21/5.5
Step-by-step explanation:
1) Since the hypotenuse is 42 for one of the triangles it must be similar to the other triangles hypotenuse, 11.
2) Therefore, the ratio is 42/11.
3)The adjacent sides to the right angle are 21 and 5.5.
4)Therefore, the ratio is 21/5.5
