Answer:
x = -7/2 multiplicity 2.
Step-by-step explanation:
4x^2 + 28x + 49 = 0
(2x + 7)(2x + 7) = 0
This is a perfect square.
2x + 7 = 0, so:
x = -7/2 multiplicity 2.
Answer:
x ≥ 2
Step-by-step explanation:
12x + 6 ≥ 9x + 12
3x ≥ 6
x ≥ 2

Radical means square root, so
3 radical 16 = 3%2Asqrt%2816%29
The square root of 16 is either 4 or -4.
Thus 3%2Asqrt%2816%29+=+3%2A4+=+12
or 3%2Asqrt%2816%29+=+3%2A-4+=+-12

"Radical" doesn't necessarily mean square root. A radical is a surd, so the index may not necessarily be 2.
3 radical 16 might mean root%283%2C16%29+=+root%283%2C+8%2A2%29+=+2root%283%2C2%29.
