The value of x is option C) x=8.6
<u>Step-by-step explanation</u>:
Given that,
- The triangle ABC is similar to triangle DEC.
- It means that the side AB of triangle ABC is in proportion to side DE of triangle DEC.
⇒ AB/DE
⇒ 11/7.
Also, the side AD of triangle ABC is in proportion to side DC of triangle DEC.
⇒ AD/DC
⇒ (x+15)/15.
<u>To find the value of x :</u>
Equating the two proportions AB/DE and AD/DC.
11/7 = (x+15)/15
Keep x term alone on one side,
x+15 = 15(11/7)
x = (165/7) - 15
x = 23.6 - 15
x = 8.6
Hello :
<span>If f(x)=x/2-2 and g(x)=2x^2+x-3, find (f+g)(x)
</span>(f+g)(x)= f(x) +g(x) = x/2-2 +2x²+x-3 = x/2 +2x²+x-5
(f+g)(x)= (x+4x²-2x-10) /2
(f+g)(x)= (4x²+3x-10)/2 = 2x²+3/2 x -5

Answer:
56
Step-by-step explanation:
im noy one hundred percent sure
the formula we use is
distance = speed * time
In the question we are provided with the info that
speed = 56 mph and
time = 3 hours 45 minutes = 3 + 45/60 hours = 3+ 0.75 hours = 3.75 hours
Now lets plug the values in the formula
distance = speed * time = 56 mph * 3.75 hours
distance = 210 miles
