Answer:
4.8
Step-by-step explanation:
The answer to your question would be shown in steps. The decimal form is -1.2. You need to do a formula called "Keep, Change, Switch," which -3/4 is kept, division is turned into multiplication, and 5/8 is switched to make 8/5. Now we do the math, so we multiply -3 by 8 and 4 by 5, giving us from a fraction, -24/20, but you can simplify that, giving us the fraction, -1' 1/5 (I put ' as in that any number to the left of ' is a whole number, not a fraction for a numerator or denominator.
Hope this helped!

4(x^2 - 1)(x - 3)(x + 3)^2 = 0
(x + 1)(x - 1)(x - 3)(x + 3) = 0
x = -1, 1, 3, -3
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
