Every positive real number has TWO<span>square roots; One is positive and one is negative. They are opposites of each other. </span>
10 is a square root of 100 because (10)(10) = 100, and ̶ 10 is also a square root of 100 because ( ̶ 10)( ̶ 10) = 100.
In general, “a” is a square root of “b” if a² = b, where “a” is a real number and b ≥ 0.
In conclusion:
<span> √(100) = </span>10<span> (the </span>positive<span> square root of 100) </span>and<span> </span>
<span> ̶ √(100) = ̶ (10) = </span>̶ 10<span> (the </span>negative<span> square root of 100)</span>

Answer:
x ≤ 1
Step-by-step explanation:
3x+4≤ 7
3x + 4 - 4 ≤ 7 - 4
3x≤3
x ≤ 1
28/4=7 Therefore 1/4 of 28 is 7
Answer:
Option (C)
Step-by-step explanation:
Two statements given in the question are,
p: Memorial Day is in July
q: Parallel lines never intersect
We have to tell the represent the symbolic notation of the compound statement,
"Memorial Day is in July or parallel lines intersect"
Here word 'Or' is combining these statements.
We know word 'Or' means Disjunction which is denoted by the symbol (∨).
So the compound statement will be denoted by p ∨ q.
Option (C) will be the answer.
