Help please I really need it

1 answer:

8 0

First write the equation 8 + 12 > x because according to the triangle property, the sum of any 2 sides have to be greater than the third side. This means that the difference of any two sides should be smaller than the third side.

So, the answer would be 4 < x < 20.

What does x equal in 1/3(6-9x)=-1/5(15x-10)?

Darya [45]

Answer:

True for all x.

Step-by-step explanation:

1. Expand 1/3(6-9x)

2-3x

2. Expand -1/5(15x-10)

-3x+2

3. Subtract 2 from both sides.

2-3x-2 = -3x+2-2

4. Simplify.

-3x = -3x

5. Add 3x to both sides.

-3x + -3x = -3x + -3x

6. Simplify.

0=0

Both sides are equal, so it is true for all x.

URGENT! Write as an expression and simplify: the tripled product of 6a and b^2

sp2606 [1]

Answer:

$216(a)^3b^{6}$

Step-by-step explanation:

Remember that product means multiply..

we have

$(6ab^{2})(6ab^{2})(6ab^{2})=(6ab^{2})^3$

$(6ab^{2})^3=(6)^3(a)^3(b^{2})^3\\ (6ab^{2})^3=216(a)^3b^{6}$
