Answer:
The perimeter is 99
Step-by-step explanation:
you do 11x9=99
A - 24!
-21 as its true value is 21
-3 as its true value is 3
if you add them together you get 24!
Hope this helped ^^
Answer:
-12x
Step-by-step explanation:
36÷(-3)= -12
Since they are similar, you need to find the ratio of similarity (I made up the term, there is probably a correct one that I can’t remember).
If you divide 16/40, you’ll find that that ratio is 2.5. So then you just multiply 16 x 2.5. You’ll get 18.
18 is the length of the top of the trapezoid.
You set 18=2x+4 and solve it algebraically. Subtract 4 from both sides.
14=2x
Divide by 2 and x=7
(You can also check that the ratio is right by 16/18 is the same decimal value as 40/45. You’ll get .88888...)
Vertical stretch means the graph stretches upward, rising more rapidly than the original, the graph is steeper than the original.
