Answer:
3.428 or 3 wholes 3/7
Step-by-step explanation:
6 : 7 = n : 4 : 2
6 : 7 = n : 4
6/7 = n/4
7n = 24
n = 24 /7
n = 3. 428 or 3 wholes 3/7
“6 sq 3 inches “ ? Explain it briefly I’m trying to understand
<h3><em>This is the range of y , Ry=R−{0}</em></h3>
<em>Answer:</em>
a = 7 & a = −7
<em>Explanation:</em>
Rewrite the equation as
(x+a)(x−a)=x^2−49
Simplify (x+a)(x−a)
x^2−a^2=x^2−49
Move all terms not containing a to the right side of the equation.
−a^2=−49
Multiply each term in −a^2=−49 by −1
a^2=49
Take the square root of both sides of the equation to eliminate the exponent on the left side.
a=±√49
The complete solution is the result of both the positive and negative portions of the solution.
a=7,−7
