Answer:
4. x = 7
5. A
Step-by-step explanation:
you can't use a calculator ?
4.
x² = 49
x = 7
5.
sqrt(4) = 2
triple root (8) = 2
sqrt(16) = 4
only sqrt(2) is a never-ending sequence of digits without any repeating pattern after the decimal point. and that is the meaning of irrational numbers. they can never be described by an expression a/b, where a and b are integer numbers.
Let's take the 2 numbers are a and b.
a + b =14
if a > b
a - 3b = -2
Subtract both numbers
4b = 16
b = 4
lesser number is 4.
It’s B because the domain(x) doesn’t repeat like the other options.
Answer:
factor the expression =2y^2 (7y+1) or simplify it=14y^3 + 2y^2
Step-by-step explanation:
If you are working out the diagonal line you need to use Pythagoras Theroum: c² = a²+b²
c² = 7²+12² = 193
√c² = c = √193 = 13.89
The length of the diagonal side is 13.89,
Hope this helps! :)
