There exists a trigonometric identity which states that,
                  sin (A - B) = sin A cos B - cos A sin B
This is very similar to the given expression with A equal to 57° and B equal to 13°. The simplified form of the angle is,
                                 sin (57° - 13°) = sin 44°

Solve the following equation.<br> x^2 + 6x − 40 = 0
jonny [76]

Answer:

x = 4 and -10

Step-by-step explanation:

Given the equation

x²+6x-40= 0

The common factors to use for the factorisation are +10 and -4

x²+(10x-4x)-40=0

(x²+10x)-(4x-40) = 0

x(x+10)-4(x+10) = 0

(x-4)(x+10) = 0

x-4 =0 and x+10 = 0

x = 4 and x = -10

6 ( y + 8 ) = 3 ( 2y - 7 )
tester [92]
There is no solutions.
      
6 ( y + 8 ) = 3 ( 2y - 7 )
6y + 48 = 6y - 21
      -48         -48
    6y = 6y - 27
    +27      +27
    33y÷33 = 6y÷33
          y=2/11 or 0.18

Hope this helps!
