The answer is A. Radical sign 3.
B because in commutative property of addition the numbers switch but they do not change the sign nor the numbers. hope this helped
D since you said it equals seven then the possible answer is out of C or D but there wasn't a negative sign so I went with the positive answer.
Let's solve your inequality step-by-step.<span>−10≤<span><span>2x−4</span><8</span></span><span><span>−10+4</span>≤<span><span><span>2x−4</span>+4</span><8+4
</span></span>
(Add 4 to all parts)<span>−6≤<span>2x<12</span></span><span><span>−62</span>≤<span><span>2x2</span><122
</span></span>
(Divide all parts by 2)<span>−3≤<span>x<6</span></span>
The formal name for the property
of equality that
allows one to add the same quantity to both sides
of an equation.
This is one
of the most commonly used properties for solving equations.
The formula tells us that if a = b, then a + c = b + c. The letters a and b stand for two separate numbers, our two twins, and the letter c
stands for what we give to each twin to keep them matching. So, for
example, if we add 1 to the left side of the equation, we must also add 1
to the right side of the equation. By doing this, we keep the equation,
the twins, the same.
Answer: correct choice is B.
