Answer:
25.59
Step-by-step explanation:
The first thing that you will do is solve parenthesis (remember PEMDAS).
(32.45-4.8) - 2.06
(27.65) - 2.06
Then do the subtraction.
(27.65) - 2.06=
25.59
Hope this helps!
Let one section be x ft long and the other one be 3x. Then 4x=28, and x=7.
The shorter section will have length 7.
You can either use the Pythagorean theorem right away (a = -3, b = 27, c = 1200) or Try factoring the polynomial to find the zeros.
I would factor and start by dividing everything by -3.
<span>-3x^4 + 27x^2 + 1200 = 0
-3(x^4 - 9x^2 - 400) = 0
If you divide by -3 on both sides you see that the -3 is now gone. 0/-3 = 0
x^4 - 9x^2 - 400 = 0
factor further or use Pythagorean theorem.
(x² - 25)(x² + 16) = 0
Solve for the x-values by setting each one equal to zero.
x² - 25 = 0
x² = 25
x is +5 or -5
x² + 16 = 0
x² = -16
x = √(-16)
Two non-real solutions
x is +4i or -4i

Answer:
B. 0.1 × 
Step-by-step explanation:
There is A Zero At the beginning of the equation.
The exponent is 3, making it 10 to the power of 3. As the exponent is positive, the solution is a number greater than the origin or base number. To find our answer, we move the decimal to the right 3 time(s):
0.1 --> 100
