The interior angle sum of a triangle is 180. so 13+29 is 42 and 180-42 is 138.
Answer:
$3222 in total; $322 more than the original price.
Step-by-step explanation:
For 36 months you pay a total of 36* 89.5=3222.0
Downpayment was 100
Total payment made= 3222+100=3322.
You would pay 3222-2900=$322 higher than normal.
What operations would the set of quadratics be closed under? For each operation, explainwhy it is closed or provide an example showing that it isn’t.Type your response here:x^2-1+(x^2+2x+1)=2x^2+2x closed under addition.(x^2-1)-(x^2+2x+1)=-2x-2 not a quadratic(x^2-1)(x^2+2x+1)=x^4+2x^3-2x-1 no above degree 2(x^2+2x+1)/(x^2-1)=1+(3x+1)/(x^2+2x+1) not a quadratich. Is there a set of expressions that would be closed under all four operations? Explain.Type your response here: Polynomials with a degree of 0, real numbers, andrational numbers.

The answer is 12. Because when you arrange the numbers like this
11, 11, 12, 13, 13
The middle number is 12
(2x+15) +x=90
- 15 = -15
2x+x= 75
3x= 75
3 = 3
x= 25
