Answer:
15
Step-by-step explanation:
Let the left side of the triangle be 2Y for the bigger triangle and then the smaller one will be Y.
Comparing the two triangle
2Y/Y = 30/X
2 = 30/X
Cross multiple
2X = 30
Dividing by 2
X = 30/2
X = 15
Answer is $23.76
Calculate 20% of 22 and add it to 22:
20% x 22 = 4.4
22 + 4.4 = $26.4
Calculate 10% of 26.4 and subtract from 26.4
10% x 26.4 = 2.64
26.4 - 2.64 = $23.76
Answer:
perimeter = sum of all sides. this is same for polygons
rect: area l×b. peri = 2(l+b)
Step-by-step explanation:
15+5 = 20
20*2 = 40 cm is the perimeter of the given figure
For this case we have the following equation:
f (x) = x ^ 2 + bx-49
Deriving we have:
f '(x) = 2x + b
We match zero:
0 = 2x + b
We clear x:
x = -b / 2
The axis of symmetry is at x = 8, therefore:
x = -b / 2 = 8
Clearing b:
b = -2 * (8)
b = -16
Answer:
the value of b is:
b = -16
