Hello,
To solve this question, a good method to use is creating an equation.
The number x being multiplied by 4 can be represented as 4x.
If this results in 25, we can create the equation:
4x = 25
To solve for x, you want to remove the coefficient of 4 from x, so we can divide by 4 on both sides (doing this we will only get x on the left side of the equation, which is what we are trying to solve for).
So, dividing by 4 on both sides, we have
(4x / 4) = (25 / 4)
x = 25/4
x = 25/4, which cannot be further simplified as a fraction. However, this can be represented by 6.25 in decimal form.
x = 25/4, or 6.25
Hope this helps!
2^10 = 1024 and 2013 - 1024 = 989
So there will be 10 + 1 = 11 digits Answer
Answer:
DE=5*8=40
Step-by-step explanation:
DE+EF=DF
5x+17x-20=20x-4
22x-20=20x-4
22x-20x=-4+20
2x=16
x=16/2
x=8
DE=5x
DE=5*8=40
√8 = √(4x2) = 2√2
4√2 =4√2
2√2-4√2 = -2√2
ANSWER


EXPLANATION
We want to solve

where

We reciprocate both sides of this trigonometric equation to obtain:

We take arctangent of both sides to get;


This is the principal solution.
The tangent ratio is also positive in the third quadrant.
The solution in the third quadrant is
