Answer:
less than
Step-by-step explanation:
.
Complete the square
since a=1 for ax²+bx²+c=0
we can do
take 1/2 of the linear coefient and square it
-6/2=-3, (-3)²=9
add that to both sides
x²-3x+9-25=9
factor perfect square trinomial
(x-3)²-25=9
add 25 to both sides
(x-3)²=34
sqrt both sides, rmember to take positive and negative roots
x-3=+/-√34
add 3
x=3+/-√34
x=3+√34 or 3-√34

Answer:
24p = 72
Step-by-step explanation:
The product refers to multiplication.
Let the number be p.
The product of p and 24 is 72.
24 × p = 72
24p = 72
Let the numbers be x = 5x+18
3(5x+18) + 4x= 16
15x+ 54+ 4x= 16
19x = 16-54
X=-38/19
X= -2
5x+18= 5 × -2+18 = 8
