Solve for x 9 in x in 12 in

Mathematics
1 answer:
devlian [24]4 years ago
5 0

Answer:

x = 15in

Step-by-step explanation:

We can use the Pythagorean theorem to solve since this is a right triangle

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

9^2 + 12^2 = x^2

81 +144= x^2

225 = x^2

Take the square root of each side

sqrt(225) = sqrt(x^2)

15 =x

What is the solution to StartFraction h over negative 24 EndFraction less-than-or-equal-to 18?
attashe74 [19]

Answer:

h greater-than-or-equal-to negative 432

Step-by-step explanation:

\frac{h}{-24} \leq 18

* multiply each side by -24 *

\frac{h}{-24} *-24=h\\-24*18=-432

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.

Lady bird [3.3K]
