8y^2 + 12x - 4y^2 + 24x
= 4y^2 + 36x
Step-by-step answer:
Referring to the attached diagram, the resultant of two forces each with magnitude F and inclined to each other at 2a equals
Ra = 2Fcos(a) ..............................(1)
Similarly, the resultant of two forces each with magnitude F and inclined to each other at 2b equals
Rb = 2Fcos(b)..............................(2)
We are given that
Ra = 2Rb ....................................(3)
Substitute (1) & (2) in (3) gives
2Fcos(a) = 2(2Fcos(b))
Expand
2Fcos(a) = 4Fcos(b)
Simplify
cos(a) = 2 cos(b) QED

Answer:
1. 136.3/53% = 257.16981...
2. 99/231.2 = 0.4282
3. 853.2/51% = 1672.94117....
4. 439.7/0.56 = 785.17857
5. 496.1/0.92 = 539.23913
6. 0.32 x 238.3 = 76.256
7. 99/376.3 = 0.26308

Answer:
Her solution is incorrect. The correct solution for the equation is x=7
Step-by-step explanation:
Sasha solved the equation <em>incorrectly</em>.
The correct way to solve this equation would be:
8x = 56
Divide both sides by 8.

You would get x=7.
This equation has 1 solution.
