Answer: 410 square km

Step-by-step explanation:

The area of each of the triangles with their base on the 10 km side is $A=\frac{1}{2}(10)(13.4)$ , so their combined area is $(10)(13.4)=134$ .

The area of each of the triangles with their base on the 12 km side is $\frac{1}{2}(12)(13)$ , so their combined area is $(12)(13)=156$ .

The area of the bottom rectangular face is $10(12)=120$ .

So, the total surface area is $120+156+134=\boxed{410 \text{ km}^{2}}$

What is the variable equal to? t • 7 = 63 t = 12 t = 8 t = 9 t = 441

iVinArrow [24]

Answer:

The variable t is equal to 9.

Step-by-step explanation:

We are given t • 7 = 63. To solve this for t, we divide both sides of this equation by 7, obtaining:

t = 63/7 = 9

The variable t is equal to 9.

How can I simplify/rewrite the 1st(top) equation into the 2nd(Botton),please show a step by step solution.

Vaselesa [24]

Answer:

see below

Step-by-step explanation:

$-2(4 - \frac{x}{2} )^{5} + C$

Think of the above as:

$-\frac{2}{1}$ * $(\frac{8}{2} - \frac{x}{2} )^{5} + C$

= $-\frac{2}{1}$ * $\frac{(8 - x)^{5}}{2^{5}} + C$

= $-\frac{2}{1}$ * $\frac{(8 - x)^{5}}{32} + C$

= $-\frac{1}{1}$ * $\frac{(8 - x)^{5}}{16} + C$

= $\frac{-1(8 - x)^{5}}{16} + C$

= $\frac{(-8 + x)^{5}}{16} + C$

Can flip it around to be...

$\frac{(x - 8)^{5}}{16} + C$
