Answer:
71s
Step-by-step explanation:
The question we have at hand is 7s² + ___ + 13s + 6² = (7s + 6)². We can expand the perfect equation " (7s + 6)² " in order to find our solution. A perfect square consists of 3 terms, and hence the term in the blanks must add to 13s to form another term.
Applying the perfect square formula : ( a + b )² = a² + 2ab + b², let's expand the expression,
(7s + 6)² = ( 7s )² + 2( 7s )( 6 ) + ( 6 )² = 7s² + 84s + 6²
84s - 13s = 71s, which fills in the blank provided.
I'm gonna do this 2 ways because I'm not sure what you mean about the line. I'm going to indicate greater than or equal to with >=.
1st I'll solve for
r/15 >= -3
multiply by 15 on each side
r >= -45
Next I'll solve for
r/15 >= 3
multiply 15 on each side
r >= 45
So depending on if that is a 3 or -3 that is how you would do it....
So did I read the problem right?
Graph it on Desmos, you'll find a match.
Answer:
Step-by-step explanation:
Simplifying
f(x) = 800(0.85) * x
Multiply f * x
fx = 800(0.85) * x
Multiply 800 * 0.85
fx = 680x
Solving
fx = 680x
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by 'x'.
f = 680
Simplifying
f = 680
What are u asking, the difference?
