You meant to say x^2 - 49 and the second binomial is x^2 - 16.
x^2 - 49 = (x - 7) (x + 7).
Set each factor to 0 and solve for x individually.
x - 7 = 0
x = 7
x + 7 = 0
x = -7
Do the same for x^2 - 16.
Here is the set up:
x^2 - 16 = (x - 4) (x + 4).
Take it from here.
The area of a circle with respect to its diameter is:
A=(πd^2)/4
If he plants roses in every other section, there will be half of the area remaining, so half of the area of the circle is:
A=(πd^2)/8, since d=8:
A=(64π)/8 m^2
A=8π m^2 and if you want an approximation:
A≈25.13 m^2 (to nearest hundredth of a square meter)
Starting with x=1, subtract 1 from each side,
(x-1)=0
Our polynomial will have multiplicity of 2 for this particular zero,
(x-1)(x-1)
and do similar with the x=-4, add 4 to each side,
(x+4)=0
So our final result is: (x-1)(x-1)(x+4)
Expand out the brackets if you need this in standard form.
34/3 = 11 1/3 = 11.3333....
Answer:
b+3(3-2b)=1-2(b+1)
One solution was found :
b = 10/3 = 3.333
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
b+3*(3-2*b)-(1-2*(b+1))=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(b+(3•(3-2b)))-(1-2•(b+1)) = 0
Step 2 :
Equation at the end of step 2 :
(b + 3 • (3 - 2b)) - (-2b - 1) = 0
Step 3 :
Equation at the end of step 3 :
10 - 3b = 0
Step 4 :
Solving a Single Variable Equation :
4.1 Solve : -3b+10 = 0
Subtract 10 from both sides of the equation :
-3b = -10
Multiply both sides of the equation by (-1) : 3b = 10
Divide both sides of the equation by 3:
b = 10/3 = 3.333
One solution was found :
b = 10/3 = 3.333
