Answer:
a =13/5
Step-by-step explanation:
f(x) = 6x − 5
f(5a) = 6*5a − 5=73
30a -5 = 73
Add 5 to each side
30a -5+5 = 73+5
30a =78
Divide by 30
30a/30 = 78/30
a =13/5
The length of the flagpole is x - 5 yards
<h3>Area of a square</h3>
The formula for calculating the area of the flagpole is expressed as:
A = L²
Given that;
A = x² - 10 + 25
Factorize
A = x² - 5x - 5x + 25
A =(x - 5) - 5(x - 5)
A = (x-5)²
Compare
L = x - 5 yards
Hence the length of the flagpole is x - 5 yards

#SPJ1
He put 10 cans in the 5th row. 1st-2, 2nd-4, 3rd-6, 4th-8, 5th-10
SINCE THATS AN ISOSCELES TRIANGLE:
AB=BC
SO 3x-4=5x-10
But we have to find x
3x-4=5x-10
Minus 3x on both sides
-4=2x-10
Add 10 on both sides
6=2x
Divide 2 on both sides
3=x
So x is 3
Now since we are looking for side AB which is 3x-4
Substitute in 3 as x
3(3)-4
9-4=5
So 5 is the answer.
