Answer:
y = the total sheets in all 5 notebooks
Step-by-step explanation:
5 = notebooks
60 = sheets
y = the total
X² - 3x + 27 = 8x - 3 аdd 3 to both sides ⇒
+ 3 + 3
---------------------------
x² - 3x + 30 = 8x subtract 8x from both sides ⇒<span>
- 8x - 8x
--------------------------
x</span>² - 11x + 30 = 0 ← <span>standard form
</span>
A. Add 3 to both sides and subtract 8x from both sides.
Answer:
m = 26
n = 13
Step-by-step explanation:
Use the sine rule
Considering the perimeter (P)

where b is the base and h is the height, then

Being the area (A)
Since it is an isosceles trapezoid;
AB=CD which means;
5y-3=6y-17
get the variables to one side and you get:
-3=y-17
Then add 17 to both sides and
14=y
Therefore y=14 is your answer
