Answer:
x = -8
Step-by-step explanation:
Given: 5(x+4)+52=-4x
Distributive Property: 5x+20+52=-4x
Combine like terms: 5x+72=-4x
Subtract 5x on both sides: 72=-9x
Divide both sides by -9: -8=x
Flip the equation around: x=-8
Therefore, x=-8
We can reject the last one: subtracting a non-zero value will result in a smaller value.
So now we have:
<span>2(A + B)
(A + B)2
A2 + B2
If all of them are mulptiplications, then they are all equivalent!
I mean by this, if what you meant is this:
</span>
<span>2*(A + B)
(A + B)*2
A*2 + B*2
If there is no sign, then the multiplication sign is implicit,
and all of these expressions say exactly the same: two of A and two of B.
</span>
