Answer:

-1(12w-6)

Step-by-step explanation:

we have

(12w+6)

<u><em>Verify each expression</em></u>

case 1) -1(12w-6)

Apply distributive property

Remember that

(-1)(-1)=1

(-1)(1)=-1

-1(12w)-1(-6)

-12w+6

compare with the given expression

-12w+6 \neq (12w+6) ----> are not equivalent

case 2) 2(3+6w)

Apply distributive property

2(3)+2(6w)

6+12w

compare with the given expression

6+12w=(12w+6) ---> are equivalent

case 3) 6(1+2w)

Apply distributive property

6(1)+6(2w)

6+12w

compare with the given expression

6+12w=(12w+6) ---> are equivalent

case 4) -1(-12w-6)

Apply distributive property

Remember that

(-1)(-1)=1

(-1)(1)=-1

-1(-12w)-(1)(-6)

12w+6

compare with the given expression

12w+6=(12w+6) ---> are equivalent

\frac{70}{5}  = \frac{20 + X}{4}

56 = 20 + X ⇔ X = 36

Answer : + 36 women

Determine the type(s) of the triangle with the given coordinates. X(6,1) Y(-2,-3) Z(0,3)
jeyben [28]

The triangle with the given coordinates X(6,1) Y(-2,-3) Z(0,3) is an isosceles triangle.

The given coordinates are X(6,1) Y(-2,-3) Z(0,3).

<h3>What are coordinates?</h3>

A coordinate system is a system in geometry that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold, such as Euclidean space, in a unique way.

We know that, Distance formula =\sqrt{(x_{2}-x_{1}  )^{2}+(y_{2}-y_{1}  )^{2}  }

Now, XY=\sqrt{(-2-6)^{2}+(-3-1)^{2}  }=\sqrt{80} units

YZ=\sqrt{(0+2)^{2}+(3+3)^{2}  }=\sqrt{40} units

XZ=\sqrt{(0-6)^{2}+(3-1)^{2}  }=\sqrt{40} units

Here, YZ=XZ

Hence, the triangle with the given coordinates X(6,1) Y(-2,-3) Z(0,3) is an isosceles triangle.

Anestetic [448]
<span>A) 2x + 4y = 14
B) 4x + y = 20
If you multiply equation A by -2, then when the equations are added, the x will be eliminated.
The solutions are:
X = 4.714285714285714
Y = 1.1428571428571428
