Answer:

960cm3 (C)

Step-by-step explanation:

What i like to do is pretend that the triangle is a cube then find the volume then divide it by two (A triangle or triangular prisom is half the size of a cube or ractangular prisom). First we multiply 8*12*20 and get the volume of a rectangular prisom, then just divide 1,920 by 2 and you get 960cm3.

Answer: x=-10, y=13

Step-by-step explanation:

$-3x+2y=56\\-5x-2y=24$

+2y-2y = 0, eliminating y is much easier. So -3x-5x = -8x and 56+24 = 80

$-8x=80\\x=-10$

Substitute x in any equations but only 1 equation (Don't substitute in both equations.)

For me, I'd substitute x in -3x+2y=50

$-3(-10)+2y=56\\30+2y=56\\2y=56-30\\2y=26\\y=13$

So the answer is x = -10, y = 13

Stels [109]

Answer:

The answer is 16

Step-by-step explanation:

2 + 2 is 4 because it's in brackets

8 ÷ 2 is 4

Since they are together this means you have to multiply them.

So 4 × 4 is 16.
