Answer:7x√3
Step-by-step explanation:
√147x^2
√49 (3) x^2
√7^2 ⋅ 3x^2
√7^2x^2 ⋅ 3
√(7x)^2 ⋅ 3
7x√3
Answer:
79
Step-by-step explanation:
60<xy<100
y -2 =x
if it is prime
y cannot be even
so y could be 1,3,5,7,9
x would then be 9,1,3,5,7
but to be between 60 and 100
x must be 7 or 9
so the number must be 79 or 57
57 is not prime so
the number is 79
Answer:
x = - 6
Step-by-step explanation:
Given
x + 5 = 1 ( subtract 5 from both sides )
x = - 4
Multiply both sides by 3 to clear the fraction
2x = - 12 ( divide both sides by 2 )
x = - 6
We can solve x + y = 0 for y: y = -x.
This is a polynomial. As with all polynomials, its domain is the set of all real numbers. The range is unlimited and is also the set of all real numbers.
