Regarding question number 47, which is what I can read well ...
Equation 4 (3x-2) ² = 36 It can be solved in the following way:
-Apply distributive property
4 (9x ²-12x +4) = 36
-We order the terms and equalize to zero
36x² -48x +16 -36 = 0
36 x ² -48x -20 = 0
The roots of this equation are
(-48 + √(48 ²-4 ×36 × -20)) / 2 ×36
and
(-48 - √(48 ²-4 × 36 ×-20)) / 2 ×36
Finally the solution is:
option C
x = -1 / 3
x = 5/3
Answer:
786
Step-by-step explanation:
6•1=6
6•30=180
6•100=600
600+180+6=786
The coefficient of -7x is -7, since -7 is the number being multiplied by x.
Similarly, the coefficient of 9/4y is 9/4, since it is the number being multiplied by y.
