Here, As the exponent and base both are different, we can't simply it by using any mathematical rule, so we have to convert them into decimal then comparing with options.
So, <span>5^3/4 + 2^11/12
= 3.34 - 1.88
= 1.46
Which is most precise to </span><span>2^7/12 </span><span>= 1.49
In short, Your Answer would be: Option D
Hope this helps!</span>
Answer:
x=1, z=-2, y=3
Step-by-step explanation:
Substitution Method
You cannot divide by zero, because that is undefined, it approaches infinity, which is not a real value. Some would say that division by zero is "not allowed" :P
So in this case the divisor cannot equal zero.
x^2+4x+3=0 There are many methods to factor, I'll complete the square, just for conciseness (and it is good to know how the quadratic formula is derived)
Divide by the leading coefficient, which is just 1 in this case...
Move the constant to the other side, subtract 3 from both sides
x^2+4x=-3 Halve the linear coefficient, square it, then add that value to both sides...(4/2)^2=2^2=4
x^2+4x+4=1 Now the left side is a perfect square...
(x+2)^2=1 Take the square root of both sides
x+2=±√1 subtract 2 from both sides
x=-2±√1
x=-2±1
x=-3 and -1
So if the equation equals zero when x=-3 and -1, it's factors are:
(x+3)(x+1)
So x cannot equal -3 or -1, otherwise your original equation would have division by zero.
Answer:
You're supposed to write both
Step-by-step explanation:
They are both classifications of a triangle but they are different kinds. Scalene, isosceles, and equalateral measure the length of the sides while acute, obtuse, and right measure the angles. Hope it helps! :)
Answer: 8 Units
btw have a good day :)
