Can someone please help me with thiss!?
DIA [1.3K]

I would first find the volume of the hole and multiply that by 2 because there's 2 holes.

v = lwh

v = (5)(8)(5)

v = 200

200 \times 2 = 400

//

I would then find the volume of the entire cinder block.

v = lwh

v = (16)(8)(8)

v = 1024

//

I would then substract.

1024 - 400 = 624

The volume of the cinder blocks is 624 inches³

stealth61 [152]

Answer:

1. X axis, 8, 3

2. Y axis, 4,-9

Step-by-step explanation:

The rule of reflections that the place opposite of the axis is negative so:

The rule for x-axis reflection is (x,-y)

The rule for y-axis is (-x,y)

For the first one, x has remained the same, so that means it’s a x-axis reflection.

So change -3 to 3

Same for the next one.

-9 is not changed so that means it’s a y-axis reflection.

And the point is 4,-9
