Answer:
The closet equivalent of the ratio of 'a' to 'c' is:

Step-by-step explanation:
Given
i.e.
a=0.63x
i.e.
c=3/8x
Hence,


Thus, the closet equivalent of the ratio of 'a' to 'c' is:

Answer:
no
Step-by-step explanation:
1 is obtuse one is acute
Its like a polynomial.
cosx=x
so it'll be like
2x^2+3x-2=0
<span>(2x−1)(x+2)
</span>
which makes your life easy because you do not have to solve cos(x)=−2 because it cannot be, so only solve cos(x)=1/2
Answer:
- 9x + 12
Step-by-step explanation:
Given
(- 7x + 4) - (2x - 8) ← distribute parenthesis by 1 and - 1
= - 7x + 4 - 2x + 8 ← collect like terms
= - 9x + 12
