Answer:

$21 in^{2}$

Step-by-step explanation:

The square in the middle has a length and width of 3, so multiply. <u>9</u>.

All of the triangles have a base of 3 and a height of 2. The area equation for triangles is

$A=bh\frac{1}{2}$

So base*height is 6. Divide that by 2 or multiply by 1/2.

You get 3. There are 4 triangles, so multiply <em>that</em> by 4. <u>12</u>.

Add 12 and 9 together, and you get:

$21 in^{2}$

I hope this helps!

5 1/3 + (-4 1/6)+ (-2 1/2)

nlexa [21]

Answer:

$-\frac{4}{3}$

Step-by-step explanation:

We are given that

$5\frac{1}{3}+(-4\frac{1}{6})+(-2\frac{1}{2})$

We have to find the value of given expression

$\frac{5(3)+1}{3}-(\frac{4(6)+1}{6})-(\frac{2(2)+1}{2})$

$=\frac{15+1}{3}-\frac{24+1}{6}-\frac{4+1}{2}$

$=\frac{16}{3}-\frac{25}{6}-\frac{5}{2}$

LCM(2,3,6)=6

$=\frac{32-25-15}{6}$

$=\frac{32-40}{6}$

$=\frac{-8}{6}$

$=-\frac{4}{3}$

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \: f(0) = -3$

$\qquad \tt \rightarrow \: f(2) = 1$

$\qquad \tt \rightarrow \: f(4) = 1$

____________________________________

$\large \tt Solution \: :$

F(x) represents the value of y on curve for given value of x

$\textsf{\large First -}$

$\qquad \tt \rightarrow \: f(0) =( 0) {}^{2} - 3$

[ since 0 < 2 ]

$\qquad \tt \rightarrow \: f(0) = 0 {}^{} - 3$

$\qquad \tt \rightarrow \: f(0) = - 3$

$\textsf{\large Second}$

$\qquad \tt \rightarrow \: f(2) = (2) {}^{2} - 3$

[ since 2 = 2 ]

$\qquad \tt \rightarrow \: f(2) = 4{}^{} - 3$

$\qquad \tt \rightarrow \: f(2) = 1$

$\textsf{\large Third -}$

$\qquad \tt \rightarrow \: f(4) = - 4 + 5$

[ since 4 > 2 ]

$\qquad \tt \rightarrow \: f(4) = 1$
