Step-by-step explanation:
step 1. a12 = -5(12) + 32
step 2. a12 = -60 + 32
step 3. a12 = -28.
Answer:
c. (x^2+1)(x^2+a)-a = x^2(x^2+a+1)
Step-by-step explanation:
You can use FOIL or the distributive property to expand the product of binomials, Then collect terms and factor out the common factor.
(x^2+1)(x^2+a)-a
= x^2(x^2 +a) +1(x^2 +a) -a
= x^4 +ax^2 +x^2 +a -a
= x^4 +ax^2 +x^2
= x^2(x^2 +a +1) . . . . . matches choice C
100+ 100+ 100+ 9= 309
200+ 50 +50= 300

<em>Overall</em><em> </em><em>Answer</em><em>:</em><em> </em>
<em>a</em><em>)</em><em> </em><em>1</em><em>2</em><em>.</em>
<em>b</em><em>)</em><em> </em><em>4</em><em>.</em>
The answer is 8.06. Follow these steps. This is an example.
a2+b2=c2
9^2+12^2=c^2
81+144=c^2
225 =c^2
Since 225 = c2, take the square root of both sides to solve for c.
225=c^2
So the answer is
±15
