Answer:
-6x^4-8x^2 or -2x^2(3x^2+4)
Step-by-step explanation:
Given expression is:

In order to write the expression in simplest form we have to multiply the terms which needs to be multiplied.
So,

Combining alike terms

Can also be written as:

See attached picture for better understanding of the problem. In the problem, the given values are the following:
hypotenuse = length of the ladder
adjacent = base of the ladder to base of the wall
Solving the angle x, we have the solution as below:
cos x = adjacent / hypotenuse
cos x = 91 / 350
x = 74.93°
The answer is 74.93°.
Nine times thirty-eight can also be thirty-eight times nine or (18 divided by 2) multiplied by 38 or like this
(18/2)times(38/2)
I hope this gives you an idea
Answer:
8.2 units
Step-by-step explanation:
Given that the only information for our triangle are 2 sides and 1 angle, we must use the Law of Cosines to find side BC
<u />
<u>Recall the Law of Cosines</u>
<u />
<u>Identify angles and sides</u>
<u />
<u>Solve for side "a"</u>
<u />
Therefore, the length of line segment BC is about 8.2 units
