B is <em>wrong</em>. The polygon is not equiangular, because ∠A ≠ ∠E.

C is <em>wrong</em><em>.</em> The polygon is not regular, because it is neither equiangular nor equilateral.

D is correct, because the polygon is none of the above.

Question 4. Quadrilateral

A is <em>wrong</em>, because AB ≠ AD.

B is correct, because every angle is 90°.

C is <em>wrong</em>, because AB ≠ AD.

D is<em> </em><em>wrong</em>, because congruent means equal, and there is no other figure to compare.

Answer:

\large\boxed{B.\ w=-\dfrac{4}{3},\ w=\dfrac{5}{2}}

Step-by-step explanation:

6w^2-7w-20=0\\\\6w^2-15w+8w-20=0\\\\3w(2w-5)+4(2w-5)=0\\\\(2w-5)(3w+4)=0\iff2w-5=0\ \vee\ 3w+4=0\\\\2w-5=0\qquad\text{add 5 to both sides}\\2w=5\qquad\text{divide both sides by 2}\\\boxed{w=\dfrac{5}{2}}\\\\3w+4=0\qquad\text{subtract 4 from both sides}\\3w=-4\qquad\text{divide both sides by 3}\\\boxed{w=-\dfrac{4}{3}}

If you apply the changes below to the absolute value parent function,
QveST [7]

Answer:

F(x) = |x|

And we need to apply some transformations. The first part is hift 8 units left. And we need to do this:

F(x) = |x+8|

Then we need to apply the second transformation Shift 3 units down. and we can do this:

F(x) = |x+8|-3

Step-by-step explanation:

For this case we have the following function given:

F(x) = |x|

And we need to apply some transformations. The first part is hift 8 units left. And we need to do this:

F(x) = |x+8|

Then we need to apply the second transformation Shift 3 units down. and we can do this:

F(x) = |x+8|-3

What are the domain and range of the function f(x) = 3x + 5
fredd [130]

Step-by-step explanation:

Here,let x = 1,2,3 and 4

Then,

Domain =(1,2,3,4)

Again,

f(1)= 3*1 + 5

=3 + 5

=8

f(2)=3*2 + 5

=6 + 5

=11

f(3)=3*3 + 5

=9 + 5

=14

f(4)=3*4 + 5

=12 + 5

=17

Therefore, Range=(8,11,14,17)
