Answer:

Side-angle-side postulate

Step-by-step explanation:

First,  you know that angle XZW = YZW because they are both 90 degrees.

Next, you know that side WZ = side WZ because of the reflexive property (they are the same side)

Lastly, you know that YZ = XZ because Z is the midpoint meaning it divides the entire thing perfectly in half

You have two sides and the included angle, so it is SAS.

What is the common difference in the sequence (-3, 2, 7, 12, ...)
IgorC [24]

Answer:

an=a1+d(n−1) a n = a 1 + d ( n - 1 )

Step-by-step explanation:

This is an arithmetic sequence since there is a common difference between each term. In this case, adding −5 to the previous term in the sequence gives the next term. In other words, an=a1+d(n−1) a n = a 1 + d ( n - 1 ) .

Please help? solve for variable and simplify each expression
natka813 [3]

11.\\3d-2(8d-9)=-2d-4\qquad\text{use distributive property}\ a(b+c)=ab+ac\\\\3d+(-2)(8d)+(-2)(-9)=-2d-4\\\\3d-16d+18=-2d-4\qquad\text{combine like terms}\\\\(3d-16d)+18=-2d-4\qquad\text{subtract 18 from both sides}\\\\-13d=-2d-22\qquad\text{add 2d to both sides}\\\\-11d=-22\qquad\text{divide both sides by (-11)}\\\\\boxed{d=2}

13.\\3x-6=2+4(x-2)\qquad\text{use distributive property}\ a(b+c)=ab+ac\\\\3x-6=2+(4)(x)+(4)(-2)\\\\3x-6=2+4x-8\qquad\text{combine like terms}\\\\3x-6=4x+(2-8)\\\\3x-6=4x-6\qquad\text{add 6 to both sides}\\\\3x=4x\qquad\text{subtract 3x from both sides}\\\\\boxed{x=0}

15.\\2(x-3)=3(2x+2)\qquad\text{use distributive property}\ a(b+c)=ab+ac\\\\(2)(x)+(2)(-3)=(3)(2x)+(3)(2)\\\\2x-6=6x+6\qquad\text{add 6 to both sides}\\\\2x=6x+12\qquad\text{subtract 6x from both sides}\\\\-4x=12\qquad\text{divide both sides by (-4)}\\\\\boxed{x=-3}

17.\\3b+4-12b+6+2b\qquad\text{combine like terms}\\\\=(3b-12b+2b)+(4+6)\\\\=\boxed{-7b+10}
