Answer:

x = 5

Step-by-step explanation:

The 2 triangles are similar by the AA postulate then the ratios of corresponding sides are equal , that is

\frac{x+x+10}{30+10} = \frac{x+10}{30}

\frac{2x+10}{40} = \frac{x+10}{30} ( cross- multiply )

30(2x + 10) = 40(x + 10) ← distribute parenthesis on both sides

60x + 300 = 40x + 400 ( subtract 40x from both sides )

20x + 300 = 400 ( subtract 300 from both sides )

20x = 100 ( divide both sides by 20 )

x = 5

Find the volume of the irregular figure. 2 cm 3 cm 4 cm [?] cm3 5 cm 7 cm 3 cm 6 cm
Paha777 [63]

Answer:

102cm³

Step-by-step explanation:

Imagine the shape as two rectangular prisms, a small one on top of a bigger one. Find their volumes individually, and then add them together:

<u>Small rectangular prism</u>

Volume=length*width*depth

=2*3*(7-5)

=6*2

=12cm³

<u>Bigger rectangular prism</u>

Volume=length*width*depth

=6*3*5

=6*15

=90cm³

12+90=102cm³

This is an economics question
Svetllana [295]
Well, for starters, this is more of a question for you than it is for me yet here's something to give you an idea.... I think don't let it get personal and leave your life stories at the door. Also, don't ask yourself, "how can this be done or worked out,", ask the people and if they're biased it's hard to tell so just hope that they leave off topic, etc... Ideas and or comments. The best I can give you.
