1.4375
<u>Step-by-step explanation:</u>
Step 1:
Let the given equation be 
To find X simplification of terms using BODMAS ( Brackets Orders Division Multiplication Addition Subtraction) is done as follows.
Step 2:
Let us expand the equation as 
Step 3:
Let us expand it further as 
Step 4:
To find X segregate X in one side and all other remaining terms in other side as follows
After the simplification the numerical value is
Step 5:
Keep X along one side and bring 48 to the denominator of another side to find X as follows
And the value of X is 1.4375
Answer:
x^2-2x-4=0
Δ=2^2-4*1*(-4)
Δ=4+16=20
VΔ=2V5
x1= (2+2V5)/2=1+V5
the answer is D
Step-by-step explanation:
Sin^-1(5/13) = 22.6
sin(22.6/2) = 0.196
Answer:
5
Step-by-step explanation:
In order to do this, you plug the point C (5,6) and the point D (2,2) into the distance formula, which was provided below. x2-x1 is 3, and that squared is 9. y2-y1 is 4, and that squared in 16. When adding 9 and 16 together, you get 25. When taking the square root of 25, you get + or - 5, but since distance cannot be negative on the coordinate plane, you get 5.
