So the formula for slope is (y2 - y1)/(x2-x1), so here that would be
(-5-(-20))/(-18-(-18)) which would simplify to
(-4 +20)/(-18+18) = 16/0 and you cannot divide by 0 so the slope would be undefined
Answer:
240, 1800, 2040
Step-by-step explanation:
First find the surface area of the shape - base = 3 x 15 x 2 + 40 x 15 + 40 x 3 x 2 = 930 m ^2
Now find the area of base = 40 x 15 = 600
Now, the cost of painting = 10 pounds for 25 m^2. SO here cost = 600 / 25 x 10 = 24 x 10 = 240 pounds.
Now cost of tiles = 600 x 3 = 1800
Total cost = 1800 +240 = 2040
Answer:
89
Step-by-step explanation:
4 x 2 + 3 [37 - (2 x 5)]
8 +27 x 3
27 x 3 = 81
81 + 3
89
24cm^2 is the answer i took the quiz
