-4y - x - (3y - 9x)...distribute the - thru the parenthesis
-4y - x - 3y + 9x....now combine like terms
8x - 7y <== or -7y + 8x
You move it backward like 0.054 times 100 is 5.4
Soln:
Let mikhale's age be X
Gabrielle's age be 3X
Sum of their ages is 44
To find,
their ages.
X+3X=44
4X=44
X=44/4
X=11
mikhale's age= 11
Gabrielle's age = 3x11=33
Sum of their ages 44
Thus we have got their ages.Gabrielle's age is 33 and Mikhale's age is 11.
Equation: w² + 12w + 36
= w² + 6w + 6w + 36
= w(w + 6) 6(w + 6)
= (w + 6)(w + 6)
= (w + 6)²
In short, Your Answer would be: Option D
Hope this helps!
