Answer:
See below
Step-by-step explanation:
Need the choices.....
essentially, you can multiply this equation by any constant to get an equivalent equation with the same solutions.
x^2 + 8x + 2 = 0 multiply both sides by '3' to get
3x^2 + 24 x + 6 = 0 <===== this will have the same solutions
or this one:
x^2 + 8x + 2 = 0 Multiply both sides by '6' to get
6x^2 + 48x + 12 = 0 <===== this will have the same solutions also
etc....
Answer:
Option (c) is correct.
Step-by-step explanation:
See the attached figure.
Here, x + y = 10 cm. ............ (1)
The height h divides the whole right triangle into two different right triangles.
If we consider the height as h, then applying Pythagoras Theorem,
h² = 6² - x² {From small triangle} ........... (2)
Again, from large triangle we can write,
h² = 8² - y² .............. (3)
Now, from equation (2) and (3) we can write
6² - x² = 8² - y²
⇒ 36 - x² = 64 - (10 - x)² {From equation (1)}
⇒ 36 - x² = 64 - 100 - x² + 20x
⇒20x = 72
⇒ x = 3.6 cm.
So, from equation (1) we get, y = 10 - 3.6 = 6.4 cm.
Therefore, option (c) is correct. (Answer)
