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.
b=11
4(b+24)=(12b+8)
4b+96=12b+8
-4. -4
96=8b+8
-8. -8
88=8b
88÷8=11
i think its A but im not sure
