Answer:
No solution
Step-by-step explanation:
Given the 2 equations
y = 3x + 8 → (1)
y = - 7 + 3x → (2)
Substitute y = 3x + 8 into (2)
3x + 8 = - 7 + 3x ( subtract 8 from both sides )
3x = - 15 + 3x ( subtract 3x from both sides )
0 = - 15 ← not possible
This indicates the system has no solution

Answer:
110.5 yd²
Step-by-step explanation:
Separate the figure into 1 triangle and 3 rectangles.
(see attached image)
<u>Area 1</u>
Area of a triangle = 1/2 × base × height
= 1/2 × (7 + 2 + 2) × 7
= 1/2 × 11 × 7
= 38.5 yd²
<u>Area 2</u>
Area of a rectangle = width × length
= 3 × (5 + 2 + 2)
= 3 × 9
= 27 yd²
<u>Area 3</u>
Area of a rectangle = width × length
= 5 × (5 + 2)
= 5 × 7
= 35 yd²
<u>Area 4</u>
Area of a rectangle = width × length
= 2 × 5
= 10 yd²
<u>Total Area</u>
Area 1 + Area 2 + Area 3 + Area 2 = 38.5 + 27 + 35 + 10
= 110.5 yd²
