Evaluate x(- y + z) for x = -1, y = 2, and z = 5.

The Answer is -45. First you need to plug in all of the numbers into the appropriate area. x(-y+7)= 5(-2-7)

Then distribute -10-35=-45.

(-3)

Step-by-step explanation:

x(-y+z)

= -1(-(2)+(5))

= -1(-2 + 5)

= +2 - 5

= -3

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
