Answer:
4
Step-by-step explanation:
3(a+2) = 26-2a
3a+6=26-2a
3a+2a=26-6
5a=20
a=20/5
a=4
Move all terms to one side
x^2 + 14x + 17 + 96 = 0
Simplify x^2 + 14x + 17 + 96 <em>to</em> x^2 + 14x + 113
x^2 + 14x + 133 = 0
Use the Quadratic Formula
x = -14 + 16i/2, -14 - 16i/2
Simplify solutions
<u>x = -7 + 8i, -7 - 8i</u>
Answer:
D
Step-by-step explanation:
Given
n² - n - 42
Consider the factors of the constant term (- 42) which sum to give the coefficient of the n- term (- 1)
The factors are - 7 and + 6 , since
- 7 × + 6 = - 42 and - 7 + 6 = - 1 , then
n² - n - 42 = (n - 7)(n + 6) ← in factored form
A triangle cannot have two right angles because the sum of all three angles of a triangle is 180. If there were two right angles in a triangle, then the two angles themselves would equal to 180 degrees, without adding the third angles. Since the degrees added up would have to equal 180 and with two right angles it would be more than 180, there cannot be two right angles in a triangle.
