How do I solve 2(x+1) + 5(2x-3)=

Maksim231197 [3]

You multiply 2(x+1) which is 2x+2.

Then you multiply 5(2x-3) which is 10x-15

Finally, you add 2x+2 and 10x-15, and you get 12x-13

The answer is 12x - 13

Hope this helps!

Answer:

Option C. $1,206\ cm^{3}$

Step-by-step explanation:

we know that

The volume of the solid Eva created is equal to the volume of the triangular prism minus the volume of the rectangular prism notch

step 1

<em>Find the volume of the triangular prism</em>

The volume is equal to

$V=Bh$

where

B is the area of the triangular base

h is the height of the triangular prism

substitute

$V=\frac{1}{2}(12)(12)(18)=1,296\ cm^{3}$

step 2

Find the volume of the rectangular prism notch

The volume is equal to

$V=(5)(1)(18)=90\ cm^{3}$

step 3

Find the volume of the solid Eva created

$1,296\ cm^{3}-90\ cm^{3}=1,206\ cm^{3}$

What is the surface area and volume to this?

Novay_Z [31]

Surface area= 2×(0.5bh)+4×8+4×8+4×square root of 2×8
=16+32+32+32root2
=80+32root2 square yards

Volume= Area of the base×height
=8×8
=64 cubic yards

(Pretty sure. My brain is meh today so don't
