Answer:

24x^3-19x^2-62x+45

Step-by-step explanation:

f(x)=-3x+5

g(x)=-8x^2-7x+9

f(x)*g(x)=(-3x+5)(-8x^2-7x+9)

=(-3x)(-8x^2)+(-3x)(-7x)+(-3x)(9)+(5)(-8x^2)+(5)(-7x)+(5)(9)

=24x^3+21x^2-27x-40x^2-35x+45

=24x^3-19x^2-62x+45

Meagan wants to make 2 1/3 batches of muffins. The recipe calls for 1 1/2 cups of sugar per batch. How much sugar will she need?
wlad13 [49]

Answer:

1 5/9 OR 14/9

Step-by-step explanation:

First we need to find out what the question is asking. How much sugar will she need if she wants to make 2 1/3 batches?

Next, we must see if we need to divide, subtract, multiply, or add. We need to divide.

2 1/3 divided by 1 1/2

Convert mixed numbers to improper fractions: 2 1/3=7/3   1 1/3=3/2

Apply the fraction rule a/b/c/d=a*d/b*c: 7*2/3*3

14/9 OR 1 5/9

bob travels from inglewood to Anytown; a distance of 20km. he walks 800m and cycles the rest of the way. What percentage of the
Semmy [17]
We can convert 20km to 20,000m. Then, we can subtract 800m (walking distance) from 20,000m which would result in 19,200m. Then we can put 19,200m and 20,000m as a fraction (19200/20000). Before we can multiply it by 100 to make it in the percentage form, we can get rid of 2 zeroes for both number making it 192/200 and then further simplifying it to 24/25 by dividing both numbers by 8. Finally to get the percentage we can multiply 24 and 100 (2400) and then divide the result (2400) by 25. The final answer is 2400/25=96 meaning he cycled 96% of the journey and walked 4% of the journey (100-96=4).
