Answer:
<u>27 cm²</u>
Step-by-step explanation:
Shaded Area = Area ABCE - Area AED
- S.A. = 6 x 6 - 1/2 x 3 x 6 [DE = 1/2AB = 1/2 X 6 = 3]
- S.A. = 36 - 9
- S.A. = <u>27 cm²</u>
Answer:
answer is yesterday was thrusdays
7x - 5y = 21....(4,?)...so sub in 4 for x and solve for y
7(4) - 5y = 21
28 - 5y = 21
-5y = 21 - 28
-5y = - 7
y = 7/5
check..
7(4) - 5(7/5) = 21
28 - 35/5 = 21
28 - 7 = 21
21 = 21 (correct)
the other coordinate is 7/5......(4,7/5)
