Answer:
A = 846 in²
Step-by-step explanation:
The area (A) of a rhombus is calculated as
A =
× d₁ × d₂ ( d₁ and d₂ are the diagonals ) , then
A =
× 36 × 47 = 18 × 47 = 846 in²
The only solution is (-3/2, 4)

Answer: 0.15.
Step-by-step explanation:This is the same as moving the decimal point two places to the left. For example, 15% is equivalent to the decimal 0.15. Notice that dividing by 100 moves the decimal point two places to the left.
a) (2a - b)² = (4a² - 4ab + b²)
b) (10m - n²)² = (100m² - 20mn² + n⁴)
c) (4x - 4²) = (16x² - 8x + 4⁴)
d)
e)

f)
