Determine if the ordered pair (−2,1) is a solution of 2x−y=−3.
yes or no

no, it is not a solution

Step-by-step explanation:

2x−y=−3.

insert the x value and y value ---> x= -2   y= 1

2(-2) -(1)= -3

simplify

-4-1=-3

-5= -3

NO

Area of shape = 10.8 m²

Step-by-step explanation:

Given:

Length of rectangle 1 = 4000 mm = 4 m

Width of rectangle 1 = 1200 mm = 1.2 m

Length of rectangle 2 = [6200-1200] mm = 5 m

Width of rectangle 2 = 1200 mm = 1.2 m

Find:

Area of shape

Computation:

Area of shape = Area of rectangle 1 + Area of rectangle 2

Area of shape = [(4)(1.2)] + [(5)(1.2)]

Area of shape = 4.8 + 6

Area of shape = 10.8 m²
