Answer:

672

Step-by-step explanation:

To find the volume of a rectangular prism, you multiply each side of the cube. This means that you will multiply any 2 factors such as 8x6 to get 48. Then you multiply 48 by 14, the last factor. 48x14=672 our is proven to be 672. Hope this helps you. Keep in mind it is almost like finding the area of a square but because it is 3D, you multiply 3 factors instead of 2 and the "area" is called volume.

. The exterior angles of a triangle are (2x+10)⁰, (3x-5) ⁰ and (2x+40) ⁰.

Pepsi [2]

The exterior angles of a triangle are (2x+10)⁰, (3x-5) ⁰ and (2x+40) ⁰

To get interior angle for each , subtract from 180

$180-(2x+10)=170-2x\\180-(3x-5)=185-3x\\180-(2x+40)= 140-2x$

Sum of interior angles = 180

$170-2x+185-3x+140-2x=180$

$-7x+170+185+140=180\\-7x+495=180\\-7x+495-495=180-495\\-7x=-315\\x=45$

$170-2x=170-2(45)=80\\185-3x=185-3(45)=50\\140-2x=140-2(45)=50$

Answer: x=45

smaller angle =50 degree

largest interior angle = 80 degrees

A and B are supplementary angles. If A = 7x - 18 and B = 8x + 3, find x.

Mila [183]

Answer:

x=13

Step-by-step explanation:

Angle A and angle B are supplementary

Supplementary angles add to 180 degrees

<A + <B = 180

7x-18 + 8x+3 = 180

Combine like terms

15x -15 = 180

Add 15 to each side

15x-15 +15 = 180+15

15x = 195

Divide by 15

15x/15 =195/15

x =13
