Answer:
6
Step-by-step explanation:
Before solve this you've to know that,
( + ) × ( - ) = ( - )
( + ) × ( + ) = ( + )
( - ) × ( - ) = ( + )
Let us solve now.
13 + (-7)
13 - 7
= 6

474 divided by 9
Turn 474 into 450 because 45 is a multiple of 9
9 x 5= 45
9 x 50= 45
Therefore 474 would be 450.
So,
450 divided by 9 equals 50
9 * -3 = -27, which is an integer.
The answer is (A).
Answer: (9,7)
Step-by-step explanation:
By definition, a rectangle is a quadrilaleral that has two pairs of equal sides.
When you plot the points given in the problem you obtain the points shown in the first figure.
Then, keeping the definition above on mind, the fourth vertex must be at coordinates (9,7), as you can see in the second figure.
