The answer is C.
You need you use Pythagoras theorem 2 times to have 2 equations with the same sides i.e. for example a2 + b2 = 81 and a2 - b2 = 9.
You can do it as you have different triangles but with the same sides.
Answer:
12 + 4x
Step-by-step explanation:
To solve this you would have to use the distributive property.
The problem would basically go like this.
4 (3+x)
(Distribute)
(4x3) (4 x X)
4x3 = 12, 4 x x = 4x
So the answer would be 12 +4x
Hope this helps :)
Answer: (x+4)(x^2+16)
Step-by-step explanation:
x^3+4x^2+16x+64
x^3+4x^2+16x+64
=(x+4)(x^2+16)
have a nice day!!
Answer:(-10,-23)
Step-by-step explanation:
Okay....the easiest way to answer this would be either elimination or graphing. However, you could also use substitution.
Right now, I'll show how to use it by elimination.
First this is to convert both equations to standard form (x+y=__)
What we'll do for the first one is add 3x to each side. We end up with this:
-3x+y=7
Then subtract 2x from the other one. Ending up with:
-2x+y=-3
Now, we eliminate the y by subtracting.
-3x+y=7
(-) -2x+y=-3
___________
-x =10
x = -10
Now, plug in the x to one of the equations.
y=2(-10)-3
y=-20-3
y=-23
Make sure to check your answer by plugging both into the equations.
X=-10
Y=-23
Hence missing value in the solution to the equation is:(-5,2)
Step-by-step explanation:
We are given the equation:
and we need to complete the missing value in the solution to the equation
(-5,?)
Since the solution is in the form of ordered pair, so first value represent value of x and second value represents value of y i.e (x,y)
So, x= -5, Now finding y:
Putting value of x in given equation:
So, value of y is 2
Hence missing value in the solution to the equation is:(-5,2)
