Answer:
If you simplify it you get d^2-4d
Step-by-step explanation:
Every calculation with multiple operations must abide to BODMAS (Brackets, Other, Divide, Multiple, Addition, Subtraction)
Thus we would multiple first, giving us 86138220. Then we would add giving us: 86145009
The answer is 4 hope this helps
Answer:
Area = 74.1 square units
Step-by-step explanation:
Area of the composite figure = Area of the rectangle + Area of the semicircle
Area o the rectangle = Length × Width
= 10 × 6
= 60 square units
Area of the semicircle = 
Here, r = radius of the semicircle
For the semicircle with radius = 
= 3 units
Area = 
= 4.5π
= 14.14 units²
Total area of the composite figure = 60 + 14.14
= 74.14 square units ≈ 74.1 square units
5) 1,512 is 5 because 12,600× .12 leaves you 1512$ dollars off the original price.
6) 15.38 or 15.4% if you round to the nearest tenth. 32,800÷ 2132 leaves you the % additional of the raise can also be written as 32,800 = 2132x divide both sides and x being the percent is 15.4%.
7) the discount is 49.90$ another one like 5. multiply 499.00 x .10 = 49.9 also said as 49.90.
