I must assume that by "15x2 - 44x - 36" you actually meant "<span>15x^2 - 44x - 36." Use " ^ " to denote exponentiation, please.
One by one, take each of the following sets of possible factors and mult. them out to determine whether the result equals </span>15x^2 - 44x - 36:
<span>
(5x - 9)(3x + 4)
(3x - 4)(5x + 9)
(5x - 18)(3x + 2)
(5x + 18)(3x - 2)
First one: use the "foil" method: (5x)(3x) + 20x - 27x - 36. This does not simplify to </span>15x^2 - 44x - 36 and so is not the correct choice. Go on to the second answer choice and continue this check.
Answer:
20a (less than or equal to) 28a
Step-by-step explanation:
PEMDAS
2a + 3= 5a
4*5a=20a
2. a+1=1a
-3*1a=-3a
-3a+31= 28a
The height of the emu is 60 inches, which the problem says is 70 inches less than five times the height of the kakapo. You can use h to represent the height of the kakapo.
In the form of an equation, this is:
60 = 5h - 70
Simplifying the equation gives us:
130 = 5h
26 = h
So, the height of the kakapo is 26 inches.
