<span>The answers are x = 2.33 and </span>x=1

3x^2 - 10x + 7 = 0
x3

x^2 - 10x + 21 = 0

After you find the factors, you divide them by 3, since you multiplied by 3 before.

(x - 7/3) (x - 3/3)

Simplify.

(x - 2.33) (x - 1)

Equal both to zero and solve.

(x - 2.33) = 0

(x - 1) = 0

x = 2.33
x = 1

George had 1 sheet of paper.He cuts it into 6 inches by 5 inches,and 3 inches by 6 inches.What were the dimension and total area

7nadin3 [17]

Answer:

A. 8 inches by 6 inches.

B. $48\text{ inches}^{2}$ .

Step-by-step explanation:

We have been given that George had 1 sheet of paper. He cuts it into 6 inches by 5 inches and 3 inches by 6 inches.

We can see that two dimensions of small parts of paper sheet have one dimension same (6 inches), therefore, one dimension of original sheet of paper will be 6 inches.

We can figure out second dimension of original paper sheet by adding the lengths of dimension other than 6. So the second dimension will be 8 inches (5+3).

Therefore, the dimensions of our original sheet will be 8 inches by 6 inches.

Now let us figure out the total area of the original sheet of paper by multiplying 8 by 6.

$\text{The total area of the original sheet of paper}=8\text{ inches}\times 6\text{ inches}$

$\text{The total area of the original sheet of paper}=48\text{ inches}^{2}$

Therefore. the area of original sheet of paper will be $48\text{ inches}^{2}$ .
