Answer: A- Selena is incorrect because she should have substituted the values for the variables first, and then simplifed
i just took the test. i know that drake is correct because his finale answer was -1/2 and Selenas finale answer was 1/2 if she would have substituted her vaules before simplifying she would have gotten the answer 1/-2 instead of -1/-2 which resulted in her finale answer to be 1/2
<span>5x-3+2(x+4) solve for x
=</span><span>5x - 3 +2x + 8
</span><span>= 7x + 5
so 7x = -5
x = -5/7

Answer:
PQRS and TUVW are similar.
Step-by-step explanation:
We are give two polygons.
Sides of first polygon are :
PQ = 8 ft
QR= 13ft
RS = 8ft
PS = 13ft.
Sides of second polygon:
TW = 2.4 ft
TU = 5.2 ft
UV = 2.4 ft
VW = 5.2 ft.
We can see that PQRS and TUVW are parallelograms.
Note: <em>If an angle of a parallelogram is equal to an angle of another parallelogram then parallelograms would be similar.</em>
We can see that <Q ≅ <T = 120°.
<h3>Therefore, PQRS and TUVW are similar.</h3>
Answer:
I'm pretty sure it would be base x height divided by 2 so 20×6÷2
