101/400 or .3025 is your answer
Minus p both sides
xy=5-p
divide both sides by x
y=(5-p)/x
B
Answer: Approximately 96 square feet
======================================================
Work Shown:
1 ft = 30 cm
1 ft = (5*6) cm
1 ft = 5*(6 cm)
1 ft = 5*(1 board width)
1 ft = 5 board widths
12*(1 ft) = 12*(5 board widths)
12 ft = 60 board widths
12 ft = 1 full wall length
The wall is 12 feet horizontally across and 8 feet tall, so its estimated area is 12*8 = 96 square feet approximately. This is approximate because of the fact we used the approximation of 1 ft = 30 cm.
2(x - 4) + 7(x + 2)
mutiply the first bracket by 2
(2)(x)=2x
(2)(-4)= -8
mutiply the second bracket by 7
(7)(x)=7x
(7)(2)= 14x
2x-8+7x+14
2x+7x-8+14 ( combine like terms)
Answer:
9x+6 or 6+9x
