Add 1/(x-8) to both sides
cross multiply or multply both sides by (5-x)(x-8)
5(x-8)=5-x
distribute
5x-40=4-x
minus x from both sides
4x-40=4
add 40 to both sides
4x=44
divide by 4
x=11
Answer:
1) 33 cm squared
2) 212.5 cm squared.
Step-by-step explanation:
1) Split the figure into a rectangle and a square. The rectangle is 8 (4 times 2) and the square is 25 (5 times 5). 25+8 =33.
2) Find the area of the shaded and unshaded. 14 times 25 equals 350. Then find the area of the unshaded triangle. 11 times 25 divided by 2 is 137.5. Now subtract. 350-137.5 = 212.5.
