Answer:

Answer choice a.

Step-by-step explanation:

Let's do part of the work of solving the given system:

6x + 2y = −6

3x − 4y = −18

Multiply the first equation by 2 so as to make the coefficient of y = to 4:

12x + 4y = -12

Combine this result with the second equation:

12x + 4y = -12

3x − 4y = −18

------------------------

 15x = -30

Note that these results are precisely the same as the equations in Answer Choice a.

How many square feet of outdoor carpet will we need for this hole
Fed [463]

Answer:

40 ft²

Step-by-step explanation:

The shape of the outdoor carpet can be decomposed into 2 triangles and 1 rectangle

✔️Area of triangle 1:

Area = ½*bh

b = 6 - 3 = 3 ft

h = 11 - 7 = 4 ft

Area of triangle 1 = ½*3*4 = 6 ft²

✔️Area of triangle 2:

Area = ½*by

b = 2 ft

h = 3 ft

Area of triangle 2 = ½*2*3 = 3 ft

✔️Area of rectangle = L × W

L = 11 ft

W = 3 ft

Area of rectangle = 11 × 3 = 33 ft

✅area of outdoor carpet = 4 + 3 + 33 = 40 ft²
