Answer:
D
Step-by-step explanation:
Because the numbers do not comply with the like 11+6+18+21= no answer and multiplying them all didn't matter either so its none of the above
I got 6 for my answer, but I'm not 100% sure if I'm right.
6(2x-11)+15=21
12x-66+15=21
12x-51=21
+51 +51
12x=72
----- ----
12 12
x=6
The result is
3x^2 + 2 + 3/2x-1
7-(-4) is 4 units from 7 in the negative direction. See the explanation and the linear scale attached.
<h3>What direction is being referred to in the above Question?</h3>
The direction being referred to is the direction of the number on a numerical scale or Linear Scale.
In the attached linear scale, we can see that the arrow stops at 11. This is arrived at by expanding the bracket:
7 - (-4)
the subtraction signs cancel out each other creating a positive sign. Hence we have:
7 + 4
= 11.
Hence, 11 is 4 units away from 7 in the negative direction. That is going toward zero is negative or a reduction hence, to get to 7 you need to go toward the negative section of the scale.
