What's next in -3x+2+9x=4x-5-1
1 answer:
Firstly, you need to combine like terms within that side of the equation.
Take -3x +9x and you’ll get 6x.
Next, combine like terms on the other side of the equation.
Take -5-1 and you’ll get -6
So far you should have:
6x+2=4x-6
Subtract 4x on each side!! Cancel 4x-4x! Solve 6x-4x!
Now you’ll get:
2x+2=-6
Subtract 2 on each side!!
Cancel out 2-2 and solve -6-2.
You should get:
2x=-8
Lastly, divide 2 on each side.
Cancel out 2/2 and solve 8/2.
Your final answer should be:
X = -4

The answer would be
<span>59 and 60.</span>
The vertex for this function would be (-2,-79)
The max occurs when length=width
so
perimiter=16
and L=W
P=2(L+W)
16=2(L+L)
16=2(2L)
16=4L
4=L
the dimentions are length and width are 4 meters
aera will be 16 square meters
