No, -4 is not a natural number. It is a negative, the only natural numbers are positiv numbers. Hope this helped!
Answer:
B)square root of 130
Step-by-step explanation:
A^2+b^2=c^2
A=7
B=9
7^2=49
9^2=81
49+81=c^2
C^2=130
Simply rearrange the terms and simplify.
Subtracting 4x from both sides, we have:
-11y=-4x-6
Dividing by -11, we have:
This is in the proper form, so this is our final equation.
Answer:
15
Step-by-step explanation:
Let 'l' be the length of the other leg
Using pythagoras theorem,
25² = 20² + l²
625 = 400 + l²
225 = l²
l = 15
Answer:
The answer is 5 ( 6 + x ) = 20
Step-by-step explanation:
Five times = You are multiplying 5 to a number(s)
Sum of 6 and some number = Sum means to add. You are adding 6 to an unknown number.
In terms of x = You do not know what you are adding 6 with. Therefore 6+x.
is 20 = The total is 20.
To solve:
5 ( 6 + x ) = 20
30 + 5x = 20 Use the distributive property and multiply 5 to the 6 and the x
-30 + 5x = -30 Subtract the 30 on both sides
5x = -10 The 30's would cancel each other out and this is what's left
5x/5 = -10 / 5 Divide 5 on both sides.
x = -2 The 5 cancels each other on the left side.
x = -2 Is your answer
Hope this helps!
