Answer:
25 square yards
Step-by-step explanation:
We assume that "fits neatly" means "fills" so that the area of the painting is the same as the area of the square. Put the numbers in the formula and do the arithmetic.
A = (5 yd)² = 5² yd² = 25 yd²
Answer:
440
Step-by-step explanation:
1) 3.8x + 5.2x - 6.7 = 11.3
9x = 11.3 + 6.7
9x = 18
x = 18/9
x = 2
2) 7.8y - 4.9 - 5.4y = 2.3
2.4y = 7.2
y = 7.2/2.4
y = 3
3)



Multiply by 3 by both sides:

Simplify:
2x = 18
x = 18/2
x = 9
4)

Do lowest common denominator:



Simplify by 5 by both sides:


Answer: smaller x = -4/3
larger x = -1
