I think it is x² - 10x + 21 = 0.
Answer:
2 in think
Step-by-step explanation:
Answer:
x=12
Step-by-step explanation:
Midpoint B of segment AC creates both equal segments AB and BC. The midpoint halves out AC therefore AB=BC
The equation would look like 2x-5=x+7 where you want to isolate x fully. First you want to add 5 on both sides of the equation so that you get 2x=x+12. Next subtract x from both sides of the equation to then get x=12.
Answer:
⇒
is the required relationship.
Step-by-step explanation:
Let us assume, the given right angled triangle is ΔPQR.
Here. PQ = Perpendicular of the triangle.
QR = Base of the triangle.
PR = Hypotenuse of the triangle.
Now, PYTHAGORAS THEOREM states:
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“
⇒
Hence in ΔPQR: 
And the above expression is the required relationship between the sides of a right triangle.
What? That’s not possible because there’s no blue pens. If that’s the awnser?
