Answer:
see below
Step-by-step explanation:
x^2+8x+26
Take the coefficient of the x term
8
Divide by 2
8/2 = 4
square it
4^2 =16
we need to add 16 to 26 = 16+10
x^2 + 8x+16 +10
(x+4)^2 +10
Answer:
If should be 10.4 for c and -3558.4 for the total answer
Step-by-step explanation:
By using the theorem

You will get 10.4.
Now plugging that number to that other formula, I got -3558.4
Hope this helped
Answer:
65 centimeters per second = 0.65 meter per second
Step-by-step explanation:
So, 65 centimeters per second = 65100 = 0.65 meter per second. To calculate a centimeter Per second value to the corresponding value in m/s, just multiply the quantity in cm/s by 0.01 (the conversion factor).
Answer:
161.91
Step-by-step explanation:
First find the side length or YT by using the pythagorean theorem.
c= 129.2^2 = 16692.64
b= 68^2=4624
c-b = 12068.64
The square root of 12068.64 is approximately 109.86.
Using that length use the pythagorean theorem again and so:
a = 109.86^2 = 12068.64
c = 57^2 = 3249
a-c = 8819.64
The square root of 8819.64 is approximately 93.91.
So, 68 + 93.91 = 161.91
Angle A and angle B sums up to 180 (interior angles)
6x - 35 + 3x + 53 = 180
9x + 18 = 180
9x = 162
x = 18
angle A = 6(18)-35 = 73 degrees
