:) Brainliest pls??
Answer:
The positive solution is 6.
Step-by-step explanation:
x^2 - 6 = 5x (Subtract 5x from both sides)
x^2 -5x - 6 = 0 (We can factor this, so there is no need to use the quadratic formula)
(x - 6)(x + 1) = 0
If the product of the two terms is zero then either one being equal to zero will cause the whole expression to be zero.
The solutions are:
x - 6 = 0 (Add 6 to both sides)
x = 6
x + 1 = 0 (Subtract 1 from both sides)
x = -1
The positive solution is 6.
Answer:
x = 14
EHF = 15 degree GHF = 75 degree
Step-by-step explanation:
(x+1) + (5x+5) = 90
(x+5x)+ (1+5) = 90
6x + 6 = 90
6x = 90-6
6x = 84
x = 84/6
x = 14
EHF + GHF = 90 degree
EHF = x+1
= 14 + 1 = 15
= 15 degree
GHF = 5x+5
= 14 x 5 (+5) = 70 + 5
= 75 degree
EHF = 15 degree GHF = 75 degree
A. Both integers are positive
C = $5.85
$5.85 = 0.35t + 0.6
-.6 -.6
$5.25 = 0.35t
