x^2 +9x +25 + 44/x-2
Step-by-step explanation:
-5x - 35 = 0
-5x = 0 + 35
-5x/-5 = 35/-5
X = -7
for 7
Yes it is right cuz 16 is the double of 8 and even the price if doubled up so the price is right
for 8
Apply the formula
the diameter is 14
Hope this helps :)
Answer:
Step-by-step explanation:
x + y = 25 ...........................(1)
{4x + 2y =64} / 2 divide the equation by 2
2x + y = 32 ........................(3)
Step Two
subtract (1) from (3)
2x + y = 32
x + y = 25
x = 7
Therefore from equation 1 we get x + y = 25
but x = 7
7 + y = 25 Subtract 7 from both sides.
y = 25 - 7
y = 18
Check
4*x + 2*y = 64
4*7 + 2*18 =? 64
28 + 36 = ? 64
64 = 64
The checks out to be the right answer.
First get rid of the last set of () by doing distributive property with the - sign
x^2 + 2x -1 - x^2 + 2x -1
=4x - 2
