(3c² + 2d)(–5c² + d)-------->(3c²)*(-5c²)+(3c²)*(d)+(2d)*(-5c²)+(2d)*(d)
then
(3c²)*(-5c²)-------------> -15c^4
(3c²)*(d)----------------> +3dc²
(2d)*(-5c²)-------------> -10dc²
(2d)*(d)----------------> +2d²
[(3c² + 2d)(–5c² + d)]=[-15c^4+3dc²-10dc²+2d²]-------> [-15c^4-7dc²+2d²]
Answer:
Step-by-step explanation:
A jewelry store is having a going-out-of-business sale. Therefore, all merchandise is marked 40% off the regular price.
The regular price of a watch is 59.95 dollars. This means that the amount of the discount would be
40/100 × 59.95 = 0.4 × 59.95 = $23.98
Therefore, the sale price of the watch would be the difference between the regular price and the amount of the discount. It becomes
59.95 - 23.98 = $35.97

Answer:
2:3
Step-by-step explanation:
So there are 9 cups of red paint
There are 6 cups of yellow paint
Now we need yellow:red
6:9
Simplify it
2:3
So the ratio is 2:3 for yellow to red paint
2(x-7)+3=2x-11
so h(f(x))=2x-11
