Answer:

(g+5)x(g-3)

Step-by-step explanation:

Edmentum/PLATO answer:

Rewrite the expression:

g+1/g^2+5g-3g-15 + g+3/g+5

Factor out g from expression:

g+1/gx(g+5)-3g-15 + g+3/g+5

Factor out g+5:

g+1/(g+5)x(g-3) + g+3/g+5

Least common denominator: (g+5)x(g-3)

I need help with this
olga2289 [7]

Answer:

x = 24.52

Step-by-step explanation:

Since this is a right triangle, use Pythagorean Theorem to solve for the hypotenuse.

Pythagorean Theorem: a² + b² = c²

24² + 5² = x²

576 + 25 = x²

601 = x²

√601 = x

How do you convert 60 miles per hour is how many feet per second? can iny one help
DiKsa [7]
That's two questions.

The answer to the second question is:  Yes.

The answer to the first question is:

Multiply 60 miles per hour by ' 1 ' a few times.  Use fractions that have
the same thing on top and bottom, since those are always equal to ' 1 '.
Then cancel units if the same unit is on the top and the bottom.
Here's how it goes:

(60 mi/hr) x (5280 ft/mile) x (1hr/3600 sec) = (60 x 5280 / 3600) ft/sec = <u>88 ft/sec</u>
