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.
Answer:
75 square units
Step-by-step explanation:
(x+10)x=3x^2
x^2+10x=3x^2
10x=2x^2
5x=x^2
x=5
Plugging in 5 into either of the initial equations yields the answer.
The solution is greater than one but less than or equal to 8.
C = 2(3.14) x r
C = 6.28 x 10
C = 62.8 yards
