Answer:
-5/4
Step-by-step explanation:
Pick two points on the line
(-4,0) and (0,-5)
We can use the slope formula
m = (y2-y1)/(x2-x1)
= ( -5 -0)/(0 - -4)
= (-5-0)/(0+4)
= -5/4
Can't see the figure, but the basic way to solve this problem is to use the formula for volume of a pyramid which is (length * width * height )/3. Slant height is just the square root of ((length/2)2 + height2) recognizing that there is a right triangle there. Since slant height increased by 4 cm when its height increased by 2cm, you know that the length/2 term had to increase by the square root of 12 (22+root(12)2) = 42=16. From there you can figure out the rest pretty readily.

Answer:
B
Step-by-step explanation:
x and 3x are adjacent angles and sum to 180° , then
x + 3x = 180
4x = 180 ( divide both sides by 4 )
x = 45
