Answer:
The answer is 1/10
Step-by-step explanation:
3+2=5+5=10 outcomes so 1/10
Hello.
A trinomial is a perfect square if the square root of the first term times the square root of the third term times 2 equals the middle term.
a) Adding 1/9:
b) Adding 4/9:
c) Adding 4 and 1/9:
Hope I helped.
If (x^2 -10) is one of the factors, that can be further factored into:
(x - sqrt(10) ) * (x+sqrt(10)) =0
making 2 of the 4 solutions equal:
3.1623 and -3.1623
I then used an algebraic long division calculator
http://calculus-calculator.com/longdivision/
to calculate:
<span>x^4 + 5x^3 ‒ x^2 ‒ 50x ‒ 90 divided by x^2 -10 which equals
</span>x^2 + 5x + 9
Using the quadratic formula, the roots of that equation are:
x = -5 + sqrt (-11) / 2
and
x = -5 - sqrt (-11) / 2
Both of those roots are not real.
I tried using online graphing calculators for x^4+5x^3-x^2-50x-90=0 but none worked.
2. For this equation,
<span>3x^2 ‒ 8x + k = 0
I used my OWN quadratic formula calculator
http://www.1728.org/quadratc.htm
and found that real roots no longer exist after "k" is greater than 5.3

Correct answer is B. Begin it with the words "Antarctica is".
<h3>
what is Antarctica? </h3>
Antarctica The least inhabited and most southern continent on Earth is. It encompasses the geographical South Pole and is almost fully south of the Antarctic Circle, bordered by the Southern Ocean. With a surface area of 14,200,000 km2, Antarctica is the fifth-largest continent, being nearly twice the size of Australia and larger than Europe (5,500,000 sq mi). Ice blankets the majority of Antarctica, with an average thickness of 1.9 km (1.2 mi).
The continent with the greatest average elevation is Antarctica, which also tends to be the coldest, driest, and windiest overall. With around 200 mm (8 in) of yearly precipitation at the shore and much less inland, it is primarily a polar desert.
