Answer:
-5 -√8 or ≈ -7.83
Step-by-step explanation:
<u>Solving the quadratic equation, to find its roots:</u>
- x^2 + 10x + 25 = 8 ⇒ The left side is perfect square
- (x+5)^2=8 ⇒ Getting square root of both sides
- x+5 = ± √8 ⇒ There are 2 roots
- x = - 5 ± √8
<u>The smallest root is:</u>
Answer:
h greater-than-or-equal-to negative 432
Step-by-step explanation:
* multiply each side by -24 *

IMPORTANT NOTE: when multiplying an inequality by a negative number you must flip the sign. So if the inequality sign was once facing the constant ( 18 ) then it will flip and face the variable ( h )
Thus,
h ≥-432
Which can also be expressed as h is greater than or equal to negative 432
Extra notes: You only have to flip the inequality sign if it's being multiplied by a negative number. Meaning if its multiplied by a positive number then the inequality sign does not flip.

thta is confusing try google
Step-by-step explanation:
Answer:
21
Explanation:
d=m/v
3=m/7
Multiply both sides by 7 to cancel it out of the right side
3*7=(m/7)7
21=m
