Answer:
C
Step-by-step explanation:
Volume in math means s the amount of space in a 3D object.
the formula is l × W × H
So you do 25 × 11.25 × 6
it equals to 1687.5.
Therefore, the volume of the brick is 1687.5
Answer:
-4
Step-by-step explanation:
let n be least.
3n-12=4(n+n+2)
3n-12=8n+8
3n-8n=8+12
-5 n=20
n=-4
Answer:
-10
Step-by-step explanation:
The equation would be -8 - (-10) = 2. When subtracting a negative, you are actually just adding a positive. It's like the two negative signs cancel each other out, so it would look more like -8 + 10 = 2. For the answer box, just put -10.
I would need see what your choices are to give exact answers, but I think the main idea here is to see that angles 1 and 3 are the same, and since the alternate interior angle theorem states parallel lines through a line, or another set of parallel lines, form equal angles on those positions, the lines that form those angles, p and q, must be parallel.
