Answer:
Step-by-step explanation:
23x + 1 = 3x - 2
23x - 3x +1 = -2
20x + 1 = -2
20x = -2 - 1
20x = -3
x = -3/20
x = -0.15
Answer:
8.0 seconds to the nearest tenth,
Step-by-step explanation:
h=-16t^2 +vt + c.
-16t^2 + 116t + 101 = 0
t = [ -116 + /- √(116^2 - 4*-16*101) ] / (-32)
t = (-116 +/- √19920) / (-32)
t = -0.79, 8.036 (we ignore the negative root)
The time in flight = 8.036 seconds.

The equations both match the slope and intercept of the graphed equations.
Can I have the pancakes instead of the donkey?
I can give you are summary of how to do it. UK geometry is somewhat different to US with regard to symbols used and names.
You need to prove that the 2 triangles BCE and ADE are congruent and then you can say that the sides are also congruent:- Sides BC and AD are equal (opposite sides of a parallelogram) Also < CBE = <ADE ( alternate angles) and < BCE = EAD ( alternate angles) So the triangles are congruent by 2 angles and the corresponding side, ( I think that would be ASA in the US).
The first thing we must do for this case is to find the relationship between the variables.
We have then:
From here, we clear the value of "Y":
On the other hand we have:
From here, we clear the value of "x":
Then, replacing values we have:
On the other hand:
Finally, the perimeter is given by:
Substituting values we have:
Answer:
the perimeter of ABCD is:
44 units
