Answer: x = 41.22 and 38.78
Step-by-step explanation:
Given the equation
4x² - 40x + 94 = 0
Using the general formula
x = -b+/-√b²-4ac/2a
Where a = 4, b= -40 c= 94
x = -(-40)+/-√(-40)²-4(4)(94)/2(4)
x = 40+/-√1600-1504/8
x = 40 +/-√96/8
x = 40 +/-9.8/8
x = 40+/-1.22
x= 40+2.22 = 41.22
and x = 40 -1.22
x = 38.78
Answer:
x = -9
Step-by-step explanation:
2x + 8( x + 3 ) = 3( x - 13 )
Dstribute;
2x + 8 ( x + 3 ) = 3 ( x - 13 )
2x + ((8)(x)) + ((8)(3)) = ((3)(x)) - ((13)(3))
2x + 8x + 24 = 3x - 39
Combine like terms;
2x + 8x + 24 = 3x - 39
10x + 24 = 3x - 39
Inverse operations;
10x + 24 = 3x - 39
-3x -3x
7x + 24 = -39
-24 -24
7x = - 63
/7 /7
x = -9
