Answer:
12 staples
Step-by-step explanation:
So the first thing we have to do is find the G.C.D (Greatest Common Denominator) between 21/4 and 7/16 which of course is 16 so your new fractions would be 84/16 and 7/16.
Now we have to divide both numbers I just used a fraction calculator for this but basically you multiply 84/16 by the reciprocal of 7/16 which is 16/7 and simplify which equals 12.
So it would take 12 staples to bind the booklet

Answer:
x = - 10, x = - 2
Step-by-step explanation:
Given
x² + 12x = - 20
To complete the square
add (half the coefficient of the x- term )² to both sides
x² + 2(6)x + 6² = - 20 + 6² ← completing the square
(x + 6)² = - 20 + 36 = 16
Take the square root of both sides
x + 6 = ± = ± 4
Subtract 6 from both sides
x = - 6 ± 4, hence
x = - 6 - 4 = - 10 or x = - 6 + 4 = - 2
Answer:
w = 11
Step-by-step explanation:
add 15 to each side of the equation
w = 15 + (-4)
w = 11
Answer:
Step-by-step explanation:
The best way to do this is to let a graphing program do it. You could do it from a chart, but a graphing program can be useful for that as well. We'll make up a mini chart here
x method y
-3 (-3)^2 + 2(-3) + 3 = 6
-2 (-2)^2 + 2(-2) + 3 = 3
-1 (-1)^2 + 2(-1) + 3 = 2
0 3
1 (1)^2 + 2(1) + 3 6
2 (2^2) + 2(2) + 3 11
3 (3)^2 +2(3) + 3 18
See the graph below.
You can pick it out from the graphs you were given.
