Answer:
Total length of ribbon to line the long sides will be 22 in
Step-by-step explanation:
In the given figure of kite if we draw a line "h" vertically will form two right angle triangles.
Then by applying Pythagoras theorem in both the triangles.
h²= (3x + 5)² + (2x + 1)² ------(1)
h²= (5x + 1)² + 5² ------(2)
By equating both the equations
(3x + 5)² + (2x + 1)² = (5x + 1)² + 25
9x² + 25 + 30x + 4x² + 4x + 1 = 25x² + 10x + 1 + 25
13x² + 34x + 26 = 25x² + 10x + 26
13x² - 25x² + 34x - 10x + 26 - 26 = 0
- 12x² + 24x = 0
12x² - 24x = 0
x² - 2x = 0
x(x - 2) = 0
x = 2
Now we will put x = 2 in the measure of sides of the kite.
Side 1 = (3x + 5)
= 3×2 + 5
= 11
Side 2 = (5x + 1)
= 5×2 + 1
= 11
Side 3 = (2x + 1)
= 2×2 + 1
= 5
Therefore, Total length of ribbon to line the long sides will be = 11 + 11
= 22 in.
-ax + 3b > 5
Subtract 3b: -ax > 5 -3b
Diuvide by - a, which implies to change the sign > to <:
x < [5 -3b]/ (-a) or x < [3b - 5]/a ..... both are equivalent
That is second option.
Answer:
I think it is 78
Step-by-step explanation:
The numbers are in the wrong order, If I put it in order, it would be 6 16 68 78 88 98. But there is no 78.
Hope this helps
Answer:
w(n) = -n-2
w(10) = -(10)-2
w(10) = -12
