Answer: see work below

Step-by-step explanation:

1) 3(2f + 4)

distribute the 3

= 6f + 12

2) 3(4t + 2)

distribute the 3

= 12t + 6

3) 7(6k -2v)

distribute the 7

= 42k - 14v

4) 5(2q - 9)

distribute the 5

= 10q - 45

(im not sure what the red mark is. if it's a negative than my answer would be opposite: -10q + 45)

5) 3(2e + 5t)

distribute the 3

= 6e + 15t

(im not sure what the red mark is. if it's a negative my answer would be opposite: -6e -15t)

6) 4(3r - 5)

distribute the 4

= 12r - 20

32. Parallelogram ABCD has vertices A(0,0), B(2,4), and C(10,4). Find the coordinates of D.
goblinko [34]

Answer:

The fourth vertex is D(8, 0)

Step-by-step explanation:

Let A(0, 0), B(2, 4), and C(10, 4) be the three vertices of a parallelogram ABCD and let its fourth vertex be D(a, b).

Join AC and BD. Let AC and BD intersect at point O.

  • We have known that the diagonals of a parallelogram bisect each other.  

So, O would be the midpoint of AC as well as that of BD.

A\left(0,\:0\right)=\left(x_1,\:x_2\:\right)

C\left(10,\:4\right)=\left(x_2,\:x_2\:\right)

The midpoint of AC is:

\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)

\left(x_1,\:y_1\right)=\left(0,\:0\right),\:\left(x_2,\:y_2\right)=\left(10,\:4\right)

=\left(\frac{10+0}{2},\:\frac{4+0}{2}\right)

=\left(5,\:2\right)

The midpoint of BD is:

=\left(\frac{a+2}{2},\:\frac{b+4}{2}\right)

so

∵  \frac{a+2}{2}=5

a+2=10

a=8

∵ \frac{b+4}{2}=2

b+4=4

b=0

Hence, the fourth vertex is D(8, 0)

A chess player won 35 of the games he played.  If his ratio of wins to loses was 5:6, how many games did he play total?
kobusy [5.1K]
42 because he won 35 so 5 times 7 equals 35 so you would multiply the other side by seven and 6 times 7 is 42
