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...)
Answer:
the answer is 3x2-10x+6=0
101.65 x .30= 30.50 saving
so take 101.65 - 30.50= 71.15
P≈9.12
area 4

Answer: GCF = 5 (5 goes into both 10 and 15)
Step-by-step explanation:
10n/5= 2n
15/5=3
if we factor it out it would be:
5(2n+3)
