Answer:
21 bushels of sweet corm weight 735 pounds.
Step-by-step explanation:
Given:
Weight of 21 bushels of sweet corn is obtained by multiplying the unit weight to the number of bushels required.
Unit weight of sweet corn is the weight of 1 bushel of sweet corn.
Weight of 1 bushel of sweet corn = 35 pounds
So, weight of 21 bushels of sweet corns = pounds.
Therefore, 21 bushels of sweet corn weigh 735 pounds.
B) No, set of side lengths does not satisfy Triangle Inequality Theorem
Given the expression (8+3i)+(-2+i)
We need to simplify it.
(8+3i)+(-2+i)
First we have to remove the parenthesis.
8+3i-2+i
As we know that multiplication of positive and negative is negative.
Now we will add or subtract like terms. Like terms means here i with i and constant term with constant term. So here we will add 3i and i. Also subtract 2 from 8.
8-2 +3i+i
6+4i
We have got the required answer.
The simplified answer is 6+4i.
Here the denominators are quadratics , so we need to factorise them first
1/(x²-5x) +3/(x²+2x-35)
factorising x²-5x ,
here GCF is x, so taking x out we have
x(x-5)
factorising x²+2x-35 using AC method,
we find factors of -35 that add up to give 2
(x-5)(x+7)
Since we have x-5 common in both denominators, so lcd of the rational expression will be product of x(x-5)(x+7)
lcd is x(x-5)(x+7)
