Question 1. I am assuming you meant 9/16, and in that case, the answer would be 0.5625. 9-16 is -7.
Question 2. 35.7% in decimal form is relative to what the percent is of. 35.7% of a million is different than 35.7% of one.
Question 3. Once again, this is relative as to what. Percentage of the weight of an elephant? It is important to specify in these types of equations.
If you would like to solve the equation 2 * x^2 + 8 * x = x^2 - 16, you can calculate this using the following steps:
<span>2 * x^2 + 8 * x = x^2 - 16
</span><span>2 * x^2 - x^2 + 8 * x + 16 = 0
</span>x^2 + 8 * x + 16 = 0
(x + 4) * (x + 4) = 0
x = - 4
<span>The correct result would be x = - 4.</span>
Answer:
4 i think or -5 +1.........
Answer:
Obtuse
Step-by-step explanation:
The sum of squares of the short sides is 130, so is less than the square of the long side. The long side (12) is longer than it would need to be for a right triangle, so the largest angle is bigger than 90°.
The triangle is obtuse.
_____
A triangle solver app or calculator can confirm this. Note angle C is about 96°, an obtuse angle.
Answer:
-9
Step-by-step explanation:
The applicable exponent rule is ...
a^b·a^c = a^(b+c)
___
For the y factor, ...
y^-13 · y^4 = y^(-13+4) = y^-9 . . . . . exponent of -9
