Given at you have an equilateral triangle, all sides have the same length.
Therefore,
First side 2x-7 = Second side x+y-9 = Third side y+5
Let us look at the second and third sides for now:
x+y-9 = y+5
x = y+5 - (y-9)
x = y-y+5+9
x = 14
Then we look at equating the first and third sides:
2x-7 = y+5
y = 2x-7-5
Substitute x =14 in the equation above:
y = 2(14)-7-5
= 28-7-5
= 21-5
= 16
The length of the third side is:
y+5 = 16 +5 = 21
Given that the length of each sides are the same in an equilateral triangle, all sides have the length 21cm.
It’s 80,610 if you really mean the tens place.
If you mean the one tenths place then it’s 80,607.2
Step-by-step explanation:
A=4πr^2=4·π·10^2≈1256.63706ft²
Answer is 1256ft^2
She will produce 2250 cysts :) 90/4 = 22.5
22.5 * 100 = 2250
