The area of the circle is 18
Answer:
No solution
Step-by-step explanation:
To eliminate is to get rid of one of the variables.
You can choose to either add each term in the equations or subtract each term in the equation.
For a variable to be eliminated, there must one pair that have the same constant with it. Each equation already has the same constant with a variable.
Try adding them.
. y - x = 15
<u>+ y - x = 5</u>
2y - 2x = 20 No variables were eliminated.
Try subtracting.
. y - x = 15
<u>- y - x = 5</u>
0y - 0x = 10 All variables were eliminated.
. 0 = 10 This is false.
This system of equations cannot be solved.
Graphically, these two lines would have the same slope and are parallel. The solution to a system is same as the point of intersection. Parallel lines never meet, never intersect, therefore there is no solution.
Equation: 2/5 + p = 4/5 + 3/5p
Simplify Both Sides:
p + 2/5 = 3/5p + 4/5
Subtract 3/5p from both sides:
p + 2/5 - 3/5p = 3/5p + 4/5 - 3/5p
2/5p + 2/5 = 4/5
Subtract 2/5 from both sides:
2/5p + 2/5 - 2/5 = 4/5 - 2/5
2/5p = 2/5
Multiply both sides by 5/2
(5/2) * (2/5p) = (5/2) * (2/5)
p = 1
Answer: p = 1
Hope that helps!!! (Answer: Letter Choice (A), p = 1
Answer:
(x + 2) (x + 4)
Step-by-step explanation:
Before looking at my explanation make sure next time you are going to ask another question write the numbers that include exponents like this: x^2 instead of x2
Factor out x^2:
x + x
Factor out 6x:
Since it is in the bx form we’ll need two numbers be add so it can be equivalent to 6x
Answer: 4 and 2
Factor out 8:
4 x 2
Now start with the 8 and 6x
(? + 4) + (? + 2)
Then finish it off with x
(x + 4) (x + 2)
