Please I need this ASAP so can someone helpppppp
iris [78.8K]
AC = 8.9
BC = 6.5
(90% angle)
8.9 x 6.5 = <span>57.85
57.85/2 = 28.925
Area of ^ABC =  28.925 cm squared

DE = 55.1
55.1/ 11.02 = 5
DEF is 5 times as big as ABC
DF = 44.5
FE = 32.5
44.5 x 32.5 = 1446.25
1446.25/2 = 723.125
I am not positive but I believe DEF = 723.125 cm squared
Good Luck on the Test!! :D

Solve for (f+g)(5) if f(x)=6x+3 and g(x)=x-4 show you work please
Diano4ka-milaya [45]
There are two ways to do this.

The first way is to algebraically find (f+g)(x) first and plug in x = 5 later. Doing that method leads us to
(f+g)(x) = f(x) + g(x)
(f+g)(x) = 6x+3 + x-4
(f+g)(x) = 7x-1
(f+g)(5) = 7(5)-1
(f+g)(5) = 34

OR

you can compute f(5) and g(5) first, then add up those sub-results to get
f(x) = 6x+3
f(5) = 6(5)+3
f(5) = 33
g(x) = x-4
g(5) = 5-4
g(5) = 1
Adding up these results gives: (f+g)(5) = f(5) + g(5) = 33+1 = 34

Either way, the final answer is 34

Multiplicity of a root means, is there that many times.

\bf \begin{cases}&#10;x=3\implies &x-3=0\\&#10;x=2\implies &#10;&\begin{cases}&#10;x-2=0\\&#10;x-2=0\\&#10;x-2=0&#10;\end{cases}&#10;\end{cases}&#10;\\\\\\&#10;(x-3)(x-2)~~(x-2)(x-2)=\textit{original polynomial}&#10;\\\\\\&#10;(x^2-5x+6)~~(x^2-4x+4)=y&#10;\\\\\\&#10;x^4-4x^3+4x^2-5x^3+20x^2-20x+6x^2-24x+24=y&#10;\\\\\\&#10;1x^4-9x^3+30x^2-44x+24=y
