Answer:

72 units

Step-by-step explanation:

There are two ways to solve the problems.

Count graphically, horizontally there are 9 units, vertically there are 8 units in the rectangle.  So the area is 9*8 = 72 units.

Alternatively, check the difference between two adjacent vertices,

1. between (4,-3) and (4,5), the difference is (0,8), or 8 units.

2. between (4,5) and (-5,5), the difference is (9,0), or 9 units.

So again, the area of the square is 8*9=72 units.

MaRussiya [10]

Answer:

She bought 5 pounds.

Step-by-step explanation:

if she spent 10 dollars and its 2 dollars per pound that means that you have to divide 10 by 2 in order to get how many pounds you can buy for 10 dollars.

If you think about it if you want 2 pounds then you multiply 2 by 2 to get four because its 2 dollars per pound and you need 2 pounds. so since you don't know the number of pounds you fill in the blanks and do 10/2 to get 5.

Bingel [31]

Answer:

9 (make sure to place the currency symbol (e.g. £ or $) beside your answer, otherwise it may be counted as incorrect).

Step-by-step explanation:

  • If one adult went and the adult tickets cost 14, we can subtract 14 from 59 to see the total cost of the children's five tickets:

59 - 14 = 45

  • Because there are 5 children, you then divide that value by 5 in order to find out the cost for one child and, ultimately, the cost of each child's ticket: 45 ÷ 5 = 9
  • The cost of each child's ticket is therefore 9
