Answer:
400/81 cm²
Step-by-step explanation:
FE : DC
1 : 3
Since area ABCD = 400
s² = 400
s = 20
FE = ⅓(20) = 20/3 cm
IH : FE
1 : 3
IH = ⅓(20/3) = 20/9 cm
Area of HIJK:
(20/9)² = 400/81 cm²
7 x 2/15
7 x 2 = 14
14/15 is your answer
hope this helps
Answer:
x = 6
Step-by-step explanation:
CT is a median, which means it divided AB into two equal parts so we can write the following equation:
7x + 9 = 5x + 21 transfer like terms to the same side of the equation
7x - 5x = 21 - 9 do the extraction
2x = 12 divide both sides by 2
<u>x = 6</u>
