Answer:

1. 25

2. 9

Step-by-step explanation:

If I'm correct, to complete the square you need to use $(\frac{b}{2} )^{2}$

So, for #1, b is 10. $\frac{10}{2}$ = 5. $5^{2}$ = 25.

For #2, b is -6. $\frac{-6}{2}$ = -3. $-3^{2}$ = 9.

Answer:

Step-by-step explanation:

If a figure A and a figure B are similar, then

$\dfrac{area_A}{area_B}=k^2$ (*)

<em>k</em><em> - similarity scale</em>

<em />

Calculate the similarity scale:

$k=\dfrac{6}{5}$

We have the surface area of the smaller prism 572 m².

Substitute to the formula (*):

$\dfrac{x}{572}=\left(\dfrac{6}{5}\right)^2\\\\\dfrac{x}{572}=\dfrac{36}{25}\qquad\text{cross multiply}\\\\25x=(36)(572)\\\\25x=20,592\qquad\text{divide both sides by 25}\\\\x=823.68\approx823.7\ m^2$

13 times 0.10 equalls 1.30
add 2.00 and 1.30
you get 3.30

8 plus 5 is 13
