Answer:
-5+5r-2 -->
--> 5r-7 <--
Explanation --
Distribute from the parentheses, of course excluding the -2 because it isn't involved, and you'll get --> -5 + 5r -2
Simplify by putting the like terms together (subtract) -->
5r -7 (you get -7 by doing -5-2, and you leave 5r by itself since it doesn't have anything more to simplify with or has any other like term)
So, the final, simplified answer -->
5r-7
Hope this helps!! Have a nice day! :)
Answer:
d
Step-by-step explanation:
The first one is 91.66666666667
The second one is 18.3333333333
Y=x² +14x +48
y-48 = x² +14x
y-48+7² = x² +2*7*x +7²
y-48+49 = (x+7)²
y+1= (x+7)²
y=(x+7)² - 1
Vertex of the function is (-7,-1). Minimum value of this function is a vertex value , because parabola directed up.
MCE = 360 - (150 + 70 + 50)
mCE = 360 - 270
mCE = 90
<CDE = 1/2(mBE + mCE)
<CDE = 1/2(150 + 90)
<CDE = 1/2(240)
<CDE = 120
answer
<CDE = 120°
