√69
Step-by-step explanation:
Step 1: Subtract 5 from both sides.
x2−7x−5=5−5
x2−7x−5=0
Step 2: Use quadratic formula with a=1, b=-7, c=-5.
x=
−b±√b2−4ac
2a
x=
−(−7)±√(−7)2−4(1)(−5)

1/6 = 1/2 of the wall
2/6 = 2/2 = 1 whole wall
2/6 = 1/3 (transforming it into simplest form)
Therefore, 1/3 of the can of paint can he used to paint the whole wall.
Hope this helps.
Answer:
a,b,e
Step-by-step explanation:
Part A) means that we have to find a composition of functions A and m
A(m(t))=π(9t)²=9πt²
part B)
A(m(t))=9πt²
A(m(2))=9*3.14*(2)²=113.04
