Using the Pythagoras theorem
15^2 = x^2 + h^2 where h = height of ladder on the nuiding
h^2 = 15^2 - 6^2 = 189
= 13.75 ft to nearest hundredth
Answer:
a = -3
Step-by-step explanation:
3a - 6a + 2 = 8a + 20 - 5a
Combine Like Terms
-3a + 2 = 3a + 20
-2 -2
-------------------------------------
-3a = 3a + 18
-3a -3a
-------------------------------------
-6a = 18
---- ----
-6 -6
a = -3
Answer:
A quadrilateral is a polygon with four sides.
Practicly anything with 4 sides like square, Rectangle ,and rhombas
Im sorry if i didn't answer your question but i did not get what you were saying but here is an image that can maybe help you
Answer:
h=6
Step-by-step explanation:
since
is an equation for a line which intersects with the curve
. The point of intersection, let's say
, should satisfy the two equations. As a result, the value of y in the second equation can be replaced with the value of y in the first equation as the following,

therefore, the latter equation can be rewritten in a quadratic equation form as the following,
= 0
if the line is tangent to the curve, it means that the line touches the curve at one point, therefore the discernment of the second order equation will be equal to zero for the famous quadratic equation solution.

where
and
, as a result, the following equations can be deduced,

therefore, dividing both sides by 12

-2a^2 - 25ab - 27b^2
hope this helps :)
