Answer:
y = x + 5: x=y−5
2x + y = 17
: x=-1/2y+17/2
Step-by-step explanation:
I do not exactly know what you were asking but I just answered the questions, if that is not what you were looking for tell me so I can try and edit my answer
Blue area = big rectangle area - small rectangle area
= 14 x 14 - 8 x 10
= 196 - 80
= 116 cm2
Edit - sorry didnt see the other person already solved the prob in comments :)
Answer:
Step-by-step explanation:
1) x² - 8x + 5 = 0
2) No subtract 5 from both sides
x² - 8x + 5 - 5 = 0 - 5
x² - 8x = -5
3) Now find (8/2) = 4. Add 4² = 16 to both sides
x² - 8x + 16 = -5 + 16
x² - 8x + 16 = 11
4) (x - 4)² = 11
5) Take square root both sides
x - 4 = ±√11
x = 4 ±√11
